Translation can't be a massive problem because they've got most of the translations done already in Tri, and the game isn't very text-based anyway.

I think the real issues are... erm... recoding some aspects? Well, definitely marketing, they'll have to spend some money on adverts if they want it to sell. Beyond that, I'm not really sure what the problem could be.
