According to various sources (here's one, and here's another), the most recent of Square Enix's "Ultimania" guides confirms that Final Fantasy Type-0 will be released overseas.
I'm guessing that if this news is true and the game is indeed being localized, it will see the light of day in North America, at the very least. So, that's not much of a worry for me. I'm also not all that worried about when it's released, as I'll probably pick it up whether it's released early or late in the year.
What I am worried about: In what formats will the game be released? I have a feeling a UMD release is the least likely to happen, which is unfortunate as that's the format I'd prefer. (I mean, just look at the game's box art, right.) A PSN release is a much better possibility, and I wouldn't turn my nose up at it unless it was too pricey.
The only way I won't be adding Final Fantasy Type-0 to my collection shortly after it's released (assuming that even happens) is if the brass at Square Enix somehow make the bone-headed decision to release the game only for Vita. They wouldn't do something so dumb, though, would they?
