Think about it a 360 Arcade with 8GB storage will be about $160.00. 16GB sticks can be had for low $30s and who knows by holidays could be in the $20s.
Also have wondered if the Xbox Dashboard gets totally Natal enabled. Could MS release a SKI that is without a standard controller. So console, Natal and Natal game for say $200.00.
Its libraries that sell systems not a single game.
