From what I've heard it seems to Xenoblade is getting released despite what Nintendo of America said. Also, I saw this on GBAtemp for Rhythm Heaven Wii:

EDIT:
Well as for other consoles and the many games that will never get released, I recommend starting with PSP and DS. Those seem to have the current biggest following, and you can manage to get a lot of help if you're a translator helping a group, whoever the hacker is probably can explain most of it.
