Based off of all the reliable speculation, I don't think the wait is going to be any longer than July-August for the At&t release of the 9000. Now, if history proves accurate, add a year or so onto that and you will have the CDMA release...

Anyway, the differences are pretty large. The 9000 comes with OS 4.6, a pretty significantly faster processor, 3G AND WiFi, as well as a higher resolution screen. There are also rumors that it will have more onboard user memory than any Berry before it. The memory rumors are the only ones still in the air really, so we just need to keep our fingers crossed in that area.
