There are confirmed rumors of a new chip/motherboard - Jasper due Q3
There are unconfirmed rumors of Blu Ray and the Xmote
The Xbox360 hasnt had a price cut for a LONG time, and since then they released the Falcon chipset. I would be peturbed if the Pro wasn't cut in price to between $300-320 around the same time or before the Jasper chipset.
Tease.
