My 2 gils about this:

PS3 version is gonna come, "at all costs", so don't worry =)

I'm doubtful with the Xbox 360 port, not because of the game, but for the service. I don't know if Microsoft will ask Square Enix to insert the Final Fantasy XIV service into the Gold or the Silver subscription. It'd be a pain in the ass for the players if they choose the Gold one, so you have to pay Gold and also the FFXIV subscription, which would suck.
If they could use PlayOnline, which runs into Silver subscription, then we would only pay the FFXIV fee.

About Wii U, I hope they're thinking about it because that's f*cking awesome!
