Check out the updates section. Confirmation of release date and existence of BD drive in the console. So i guess you could start/stop laughing?

The Xbox 720, according to the report, will pack a "monster" 16-core IBM PowerPC CPU along with a GPU equivalent to AMD's Randeon HD 7000-series graphic cards and a Blu-ray drive.

Meanwhile another report, by VG247, has emerged revealing details Microsoft has made available to certain partners. Apparently, the console will have two GPUs. The structures of the GPUs will not be as they normally are in PCs, where the two chips take turns to draw lines of the same objects. Instead, the Xbox 720 chips will, it is belived, be able to work independently, drawing different items simultaneously. 

Furthermore, according to a report by Xbox 360, Level artist Mark Ziemak from developer CD ProjektRED, has been quoted stating the Xbox 720 will not be much different from Xbox 360, when asked if the arrival of a new Xbox would drastically alter CD Projekt's multiplatform plans.

"I guess once you get the experience with consoles, with Xbox 360, then we are hoping that this experience in the future will help us in the developing games for a next gen. If next gen is around the corner pretty soon, then we are hoping the experience that we got at this moment will actually help us in creating the games for other consoles. I don't think they'll be so much different. I hope they won't be so much different that we have to totally change our control and stuff like that," said Mark Ziemak, a Level artist from developers CD ProjektRed, in a report by Xbox 360.
