My guess is as follows:
If Natal is a total flop, Microsoft stops press and support for it and allows it do die a slow death while never actually admitting it was a failure until years later. Focus will then be placed entirely on the xbox 720.
If however Natal is a success, expect the xbox 720 to also utilize it, after all if it's just an advanced controller making a much more powerful system that's also compatible with it should be simple.
