I'm going to offer up another hypothesis. Apple has a dying iPod line right now. All of the products in it are stale. Even in 2012, they got a pretty solid update (at least to half of them), but there's not much else that you can do to innovate on them as a whole. The most innovative idea was the wrist-band for the sixth generation iPod nano and that may have started the iWatch phenomenon/nonsense. But that's it.
The iPods have always been about "x thousand songs in your pocket" and with an increasing screen size of the iPod touch from 4" to 4.7", it's starting to become less of a small device. Also, whether it is due to the A6 not being thermally efficient or not, the fifth generation iPod touch was a year behind out of the gate, which is sad. They have now skipped a year making it two behind and unlike the first generation iPad mini that was released right around the same time, there is no modern successor to it. I'd love an A8 iPod touch with the iPhone 6 form factor; hell, I'll even settle for an A7 iPod touch with the iPhone 6 form factor or even the current form factor; but alas, I don't think that we'll get either.
This being said, Apple could kill all four iPod product lines, replace it with a single model, give it the iPhone 4S's 3.5" retina display and multi-touch, slap it with 128GB and 256GB flash storage capacities, slim the bezels down from what you currently have on the iPhone 4S (you don't need cameras, or an earpiece, and you could certainly slim the area by the home button (as well as the 4S home button itself), and you could slim it by a bit since it doesn't need cellular radios either. If you want to throw in the ability to side-load some iOS apps via iTunes, fine, I guess, but that's not its explicit purpose. Maybe give it WiFi for iTunes Radio and an iOS 7-inspired UI, and boom, call it "iPod". Or seventh generation iPod. And that'll be the final wave the iPod rides out on. No more iPod touch (bummer), no more iPod classic, no more iPod nano, and no more iPod shuffle. It'd be portable enough for any situation, more capacious than any iPod touch ever was and better than any non-iPod touch iPod has ever been in terms of ability. This sounds like a logical way for Apple to phase out the iPods without fully doing so. That said, I hope they don't go that route as I do like the iPod touch and the iPod classic, as well as the shuffle.
Anyway, the following quote from mangomind is worth bearing into mind.
Actually, the internals of the iPod touch have varied widely compared to the corresponding iPhone.
2007 1st gen: same processor/ram
2008 2nd gen: processor is clocked higher
2009 3rd gen: same processor/ram, one iOS version less
2010 4th gen: half the ram and the ram is slower, one iOS version less
2012 5th gen: same processor/ram as the previous iPhone
That being said:
With the iPhone's getting thinner and thinner, I always wondered how the Touch would still be relevant.
I couldn't vote.
I believe it will get an A6 this September. They'll do to it whatever happens to the iPhone--bigger screen, etc. However, they will only use an old A6 to cut costs.
Is there a real need for an A7? No. It would be nice if they used one in the next iPod Touch, but we have to deal in reality. This is not an Apple flagship product, and it never was, so it isn't going to get current tech that costs a good amount; it will be an iPad Nano at best.
There's always a need for any currently shipping computing device to not have two generations of processing power less.
I truly hope we get another model released, even if it's the last one.
Same. Hell, I even hope it isn't the last one. Though I think both scenarios are unlikely, sadly.
Yeah, I just hope they aren't all so confusing... I mean, why have the camera only on certain models... that's not the type of thing Apple usually does...
The lack of a rear-camera on the 16GB model is really for them to "justify" the lower price-point. I think it's sort of dumb, but whatever. I bought one in addition to my 64GB Blue one just for the hell of it; I also like the silver backing and black front face combo; seemed reminiscent of first through fourth generation iPads. But yeah, that model was mainly intended to replace the fourth generation iPod touch ahead of WWDC where it would be announced that said iPod touch would not be receiving the iOS 7 update.
I agree with several of the other comments here, the most likely next step isn't listed in the survey: a spec bump to an A6 processor. Apple has just dropped the iPad 2, which was the only other device still running the A5 processor, and there's no point keeping it just for the iPod Touch so I think they'll keep the same iPod Touch form factor and give it a small spec bump.
The Touch is very price sensitive - it doesn't sell well at its full price but it flies out the door whenever they post stock on the refurbished store with a big discount so a more substantial spec increase to an A7 or A8 processor, and the price rise necessary to cover it, is just wishful thinking.
I think there's probably a technical reason that touch and the first generation iPad mini both didn't get the A6 to begin with. I remember reading that it wasn't thermally efficient. They do seem to not care much about the iPod touch, but I imagine that if the line continues at all, we'll at least get an A7 in tow.
Good questions, I think the 5th Gen Touch was the first time the Touch did not match the iPhone chip spec.
Unless you count the RAM discrepancy between the iPhone 4 and the fourth generation iPod touch, then yes, you're right.
I think the iPod touch will get an A6 processor in it's next update and will stay with a 4 inch display.
I think they'll either kill it or do what I suggested they might above long before that happens.
Touch 6:
4.7" display (not the same exact display as the iPhone 6 because of the thickness of the Touch).
A7
1GB RAM
If they're continuing it, this would seem more likely based on trends. Though a lot about iPod touch trends seems uncertain at this point. Hence the topic itself.
