As part of this morning's TGS press release by Microsoft there were 4 more XBLA games announced. Gyruss, New Rally-X, and Rush'n Attack will be available everywhere, but Yie Ar Kung Fu will be exclusive to Japan.
As far as I can tell this is the first time that we've seen a territory locked XBLA game, as soon as it's out I'll be setting up a Japanese account to try it out as it's the game I want the most from this list.
You can check out the whole press release here.
