You think we'd see a Nexus tablet with an Intel processor? Obviously Intel would love that, but with most of Android running on ARM, it would seem an odd choice to make the "developer" tablet running on Intel.
32 bit or 64 bit really doesn't matter at all right now to end users anyway. So either way, don't think I'll get excited.
2560x1600 display seems likely. Everyone is doing it now.
ASUS did an okay job on the first Nexus 7 and a great job on the second Nexus 7. If HTC is making the next Nexus tablet, I really hope they continue with the design that the Google/ASUS tablets have been using. The Nexus 7 2013 is probably the best tablet I've ever held in my hand. I really love that soft touch back. Hope they don't change that for the sake of change.
I think HTC could do a good job. Though I went to their website and see no tablets mentioned, so guess that's not something they've done in a while. But the HTC One phones seem to be very well made. And hopefully they'll put forward facing speakers on the Nexus tablet if they make it.
Android 5.0? I wonder. Could just as easily be Android 4.5. Dunno if Google really has anything so amazing that they want to bump up that first digit just yet.
I'm kinda hoping for an 8 inch display. I still want something really comfortable to use one handed. 8.4 and up kinda gets big using as an e-reader one handed.
