TP2 and WM7

[fr8tdog]

Noob here with a very noob question.

I'm considering getting a TP2 thru Verizon. I've been reading here about the pending release of WM7. Do the guru's here think that a TP2 running 6.5 would be upgradeable to 7? Or should I wait for what ever version TP HTC comes out with running WM7.

Intended uses for this phone:

1) Overseas phoning home to the states either thru a VoIP type service or just swapping out the sim. (You purchase mins. on the sim for whatever country your in. Do you still have to pay overseas charges phoning the states??)

1a) After reading some of the stickies, I'm also mulling over using the tether method to phone home. Still working thru the learning curve on that.

2) Win based productivity programs needing a stylus for work .

3) Entertainment.

TIA

P.S. Great site you folks have here. Lots of info.
