I think everyone right now is waiting for the thunderbolt to drop. I was supposed to be in the hands of people as early as the 14th of last month but apparently technical difficulties had caused many delays. Mid march seems a possible release time frame.
It all depends on what specs you want. Verizon has a pretty nice variety of Android phones, I would just do a little research and see which best suites you. If you can wait until mid or late March I would hold out and get the Thunderbolt. That's just my opinion but the thing will be a beast.
