The newest BlackBerry released by Sprint is the 9670 Claimshell. As far as what cool things a BlackBerry can do is really an open ended question. Let me ask you this. What would you like your phone to be able to do?
The Torch sounds cool. Then again, I'd feel like I was learning a whole new phone. I might want to just upgrade my 9900. So, I see they also have a new software launch (QNX) planned for 2012. So, I can see why some people might want to wait.
