Not a huge place like your thinking, but Nippon Ichi had a press announcement that they are now developing Xbox 360 games.

Nippon Ichi is a hardcore RPG developer/publisher in Japan. Their primary titles include the uber-SRPG series "Disgaea". Disgaea 2 sold somewhere around 150,000 units in Japan, and about 300,000 worldwide or so.
Other titles include Altier Iris, Phantom Brave, and a few other games. They produce RPG's almost exclusively, and most are Strategy RPGs. This is great news if your like me, and crave more RPGs to your X360.
So what does this mean? Disgaea 3 might either be multiported to Xbox 360, or X360-exclusive which would be rather huge, as the NI fanbase is rather rabid.
Back from the dead, I'm afraid.
