They are most probably going to announce in some kind of media event; I have little doubt about that. That wasnt the point I was trying to make (against).
I understand the point you were trying to make. What I'm saying is that the iPad mini was the centerfold announcement at the October 2012 event (despite the thinner iMacs, the Ivy Bridge Mac minis, the introduction of the 13" MacBook Pro with Retina, and the fourth generation iPad). I agree that Apple doesn't need an iPad-only event. However, an iPad Pro along with an iPad Air would be the centerfold announcement as it is a headlining act for them still.
My argument isn't that they won't make a separate iPad event, nor that they need to. (And I guess that's where you and I are in agreement.) My argument is that the iPhone and the iWatch will be big enough on their own that adding in iPads would be too much.
It merely tagged along the presentation of the mini. New display coating and shaving off a mm on the case is, as you say, nothing to write home about. A faster processor is a given. I cant quite see why they shouldnt include it tomorrow. Now, dont get me wrong, I dont think that they absolutely will do tomorrow. I think it also depends on what they have else they have to show before the holiday season, to align the next iPad with.
We have new Mac minis and new MacBook Airs, both of which are rumored to be seeing huge redesigns, plus OS X Yosemite. MacBook Pros are on a strict 8-10 month cycle and we just saw a refresh a couple months ago, so that's out. Potentially Haswell E Mac Pros, but I'm skeptical. The last couple years, there's been plenty to stuff into that October event, and the iPads have fit in nicely.
That said, while none of the individual improvements rumored for the iPad Air are worth writing home about, there are already enough of them that would get me excited if I was due for an iPad upgrade (or upgrading from a third generation iPad or older). They are certainly enough for me to be upset about NOT seeing in the next iPad mini if this rumor is correct, that's for sure.
That something else might be a redesigned MacBook, a higher resolution iMac, the rumored watch accessory, or a new Apple TV, for all I know. But the iPhone 6 presentation seems just as good a bet to me this year (which is why Id find a release tomorrow by no means hardly shocking).
As does the iPad "pro", of course. Though I'd bet money against such a thing this year.
Samsung is pushing competition against Apple, which is awesome. The watch effort is very likely done out of that competition. I think a larger tablet could very easily be out this year. As for whether I think it'll be out this year, I give it 50-50.
