My wife and I will get it on the PS3 and the PC (since we have one of each) and switch out. I've seen all of the videos, and it looks like it will be the best that anyone could do for a console playing MMO. I never went that route with XI, but they have changed so much since then. Also, most probably already know this, but it is confirmed that if you get the PS3 version and want to get a PS4, then you are able to transition your account.
