1) I'm afraid that everyone who enjoyed FF VII once isn't interested in a remake anymore by the time Square-Enix starts to build it. Tbh, I'd rather see them combine, Crisis Core, Before Crisis and FF VII and combine it into one ultimate game or something like it. If possible offcourse. Based on the demand for it, I still expect it to come.
2) It will strongly depend on userbase, but for now: PS3. Allthough the 2 above me give enough proof that S-E has done otherwise in the past.
3) I think Sony is willing to pay for this as an exclusive. Timed is also a possibility offcourse, but I expect it to be fully exclusive.
EDIT: I would agree that I would hate it to see it go to the Wii. Allthough it's a possibility. At least I will be happy to see that I played and own the original copy of the game.
