BoyGenius has some of the specs for the oncoming (release date unconfirmed as of yet) BlackBerry 9000:
On Board Memory: 1GB
Processor: Intel XScale PXA270, at 624 MHz. That's faster than the iPhone 620 MHz, achieved via the ARM 1173;
3G Support: Yes, via multi-band GSM.
Camera: 2 megapixels, but that might be bumped up to 3.2 at launch. Which, given that the trend line in new handset cameras is toward 3 megapixels and more, you can just about count on, IMHO.
