CeBIT has begun, & TweakTown have already started posting their coverage. You can find part one here, & part two over here. Some good info on DDR3 & shots of nVidia's upcoming MCP73 chipset.

The TechReport guys decided to wait & write up their coverage of GDC '07 all at once. They have a decent five page write up that covers pretty much everything; including a booth babe, even ;)
