I read somewhere that wifi AC and USB 3 exceed the read/write speed of the internal storage. If that's the case (not sure) we will need other upgrades internally to even make them useful. However it would be nice to have them just for compatibility sake since the new iMac has both and supported by the airport devices.
 
"What are you gonna use it for" can be applied to all items on your wishlist. Just because somebody has some other wish, does not make it useless, 128GB is important and no one is going to force you to buy it, it'll be even better for you, cause it'll most likely push down the high capacity into a lower price segment.

As for my wishes. They are:

A real breakthrough in the camera department, something amazing.
2GB RAM
128GB storage, again I don't need 128GB, but I hope it'll push 32GB down in price.
USB 3.0
H.265 Hardware Decoding
aptX BT

why USB 3.0 other than say it has USB 3.0? the SSD inside can't even saturate 2.0 right now.
 
I'm starting to save up for the next-gen iPhone. I'm currently holding on to my iPhone 4S still. The TouchID, better rear camera in low-lighting, and 64-bit A7 chip are definitely great improvements. But I need to get more than those before willing to upgrade, here are more things that I hope to be added onto the iPhone 6 next year...
1. Larger screen (4.5"~5")
2. Better front camera for self-portrait
3. Waterproof & shockproof
4. Thinner bezels
5. Earphone slot to be moved to top for improved built-in speaker performance
6. Black-gold iPhone color option
7. Even bigger battery to compensate for the larger screen

  1. I would love 4.5-4.7". Anything larger would be too much.
  2. Better front camera seems logical but nothing pressing for my personal taste.
  3. I'm not sure that'll come in the next generation.
  4. Absolutely, especially with a larger screen.
  5. I actually prefer the headphone at the bottom, since I put my phone in my pocked upside down for when I'm using it as an iPod.
  6. Not remotely interested in this colour.
  7. Better battery for sure!
 
1. Larger screen (4.5"~5")
2. Better front camera for self-portrait/ Better rear camera
4. Thinner bezels
7. Even bigger battery to compensate for the larger screen at least 2200 mAh

My wishes..
 
A battery strong enough to jump start my car.

An App to turn the phone into a warming plate to keep my coffee warm.

A built in cash dispenser so I don't have to hit an ATM.

There's more, but those are my main wants.
 
Does Apple really want to gain marketshare over Android or not? If so, build a larger iPhone!
 
I don't care if Apple builds a bigger screen for those that want it as long as they keep the current size for those that love it. I thought the change from the 3.5 to the 4 inch screen was dramatic and just about perfect for me. I have kind of average to maybe slightly smaller hands for a woman and I'm able to use the 5/5S one handed for most things. I wouldn't be comfortable using a larger screen single handed for a lot of the apps I use on a daily basis let alone actually holding it up to my ear for any length of time when using it for calls.
 
I like the current phone size, I just think they need to make the screen edge to edge with almost no bezel that way scree. Is bigger without changing the form factor.

Better camera is always nice
Better front camera
At least 32gb as min. Storage
Longer battery
Ability to pay using credit cards etc from phone at restaurants etc
Enable customization of control center in ios
Ability to stream content to any smart tv or laptop without Apple TV
