While the P35 chipset from Intel is openly shown at CeBIT, the G33 is a bit harder to be found. DigiTimes says this IGP chipset can only be seen behind closed doors.
As with the P35 the G33 supports DDR3 and/or DDR2 memory, front side bus speeds up to 1333MHz, and is designed to support Intel's upcoming Wolfdale and Yorkfield CPUs. The G33's IGP supports DirectX 9 and is scheduled to launch in the second quarter, according to sources.
Our Taiwanese colleagues also reveal some info about the high-end Intel X38 chipset:
Intel will expand the Bearlake family in the third quarter starting at the high-end with the X38. The successor to the current 975X Express chipset, the X38 also supports FSB speeds of 1333MHz and upcoming Wolfdale and Yorkfield CPUs, but unlike the P35 and G33 will not include legacy support for DDR2. X38-based motherboards will only support DDR3, but in the high-end market this makes sense. The X38 will also feature support for PCI Express (PCIe) 2.0 which offers double the bit-rate of current PCIe for higher bandwidth – up to 5GT/s. X38-boards will support two x16 PCIe slots, but it is unknown whether Crossfire and/or SLI will be possible due to licensing issues.
In the third quarter we can also expect the G35, this one is similar to the G33 but supports DirectX 10.

Given that initially DDR3 will be not favored by enthusiasts, it's pretty much putting this chipset into the dustbin for a year by forcing it to be DDR3 only.
I thought Intel learned by now that you don't force enthusiasts, you entice them. DDR3 will eventually be good, but it's going to take quite a while.
Probably Intel wants to avoid the comparison of the 975 to the X38 on an apples to apples basis, likely because they know the truth won't be so pretty. Oh well. Wait till they see the utterly pathetic sales of this thing.
