@OP:
Good for MS, but 70-80% of publishers can mean anything and its opposite. It could even be only ONE game each and put together with minimal efforts and resources. Or it could mean the most probable thing, besides a few special titles, simply adding Natal support to whatever game it's simple and not counter-productive to do so: this one could be not a particularly exciting opportunity for Natal, meaning it wouldn't be a revolution, but it would considerably ease its acceptance without anybody getting hurt. Bach is right saying MS must show the way, as publishers aren't gullible peasants that MS can lure into fighting a revolution on its behalf.
