Well, kind of disappointing that they still didn't give a solid release date; but your info does give us some new insight... we now know it should be 3G to start and that it should be running the new HTC Sense UI. Up until now the 3G/4G question was up in the air, and everything that's been posted of this phone showed it with the old UI.
Anyway, thanks for the tips! Did you happen to notice if it is still Bing'd out?
Now, if only it would be announced already...
