I know that SF4 will make it onto PC, but am I mistaken that SSF2THDR is also going to be released for the PC as well (in addition to Puzzle Fighter HD)? I don't have one of the current consoles as I do most of my games on PC. With the advent of being able to use a 360 controller on the PC and with many games supporting and configuring it automatically, it has made some console to PC ports essentially play like an Xbox 360 game. I could see "friends" interaction and matchmaking through Steam as a viable option.

I hope so. That would be bomb. Can't say I know though. :(

No.

This is a remake, so no. You can get the original version on the PC I think.
