I am curious as well, its been a month since it has been officially announced and not a single word about it since. Then you have the htc sensation that was announced two weeks ago and it seems like you hear stuff about that phone all the time since. I am starting to wonder that the specs or design of the evo3d may not be final after all and that they may be making some last minute tweaks to the hardware.
I've been thinking the same thing, and that'd be pretty awesome. I'd speculate maybe permanent clocking at 1.5 gHz since that benchmark came out and that was the speed, and also since Samsung recently gave the GS2 a bump to 1.2, I could see hTC wanting to keep a leg up over the competition. I'd also maybe speculate increased internal storage since 4GB is a pretty random number(Phones usually have 1-8-16-32). An increase to 8 would be awesome and an increase to 16-32 would be godly(Although I want hold my breathe on that one). Finally what'd have me most excited is the addition of a kickstand to the battery cover since now they see how much people are mad that they took it away. This is all speculation of course, but who says I guy can't hope?
