I found this article and thought it was definitely worth sharing:

I just received an email from one of our readers whose been full of good info in the past. They’re apparently privvy to the AT&T roadmap for 2008. Most of the information seems to agree with what’s been speculated about. Lots of WM 6.1 refreshes and some slightly updated models

And the best part:

Samsung Blackjack 2 6.1 upgrade due in July

And the next curious part, a Blackjack 3 slated for late 2008:

Samsung Blackjack 3 due in Q4 this year, specs below:

Windows Mobile SP 6.1
Tri-band HSDPA (3.6); Quad-band EDGE
528 MHz processor
128MB RAM/ 256MB ROM
Camera 3 MP
AGPS
VSC
WiFi

Launch Target: late Q4/08

That all made sense to me except the "VSC". After some digging, it appears the BJ3 will have a VSC Touch Screen.
