I thought it was to be released next week? and if the Pure has it, my assumption is its out in limited fashion?
Here is the thing, the CORE OS is released. BUT, you won't see an "OFFICIAL" ROM release until HTC has tweaked and bloated it, THEN AT&T (or other carriers) Tweak and Bloat it and THEN they will release it for their CURRENT Handsets, meanwhile, all their Dev time is going into their NEW handsets to try and entice you to upgrade to get it NOW rather than wait for them to decide to release something.
I used to work for AT&T and now work for T-Mobile. I will tell you that T-Mobile is WAY... WAAAAAAAYYYYYY better at giving the customers what they want than just about any other carrier. That is why we embraced Android. Withing DAYS of the 1.5 and 1.6 released we were sending out OTA updates for handsets. AT&T never did anything that fast unless they were forced too due to some kind of mass issue or whatever.
Consumers have more power than they realize, they just don't speak up loud enough.
