Rumour: Microsoft to announce "Xbox Lite" for $100 in late 2013.

I could see this happening instead of lowering the price of the current Xbox: introduce a smaller Xbox and discontinue the old one - everybody knows that redesigns sell well (that's how Nintendo makes their money;p)! And 3-4 months later they'll launch the nextbox, that way they won't lose as much money on the nextbox ;)
