Intel will focus on the Intel G45 chipset this year.
If you notice, AMD and NVIDIA are also doing something similar, having IGP products functioning as discrete chipsets.
This seems to be the trend these days. Intel G45 will come with a more powerful GPU integrated that supports DX10. The G45 will also support DP/HDMI/DVI/VGA output.
It is said that the quoted pricing for Intel G45 and P45 are the same. Thus, we should probably see more vendors selling the G45 variant, probably with 2 PCIe full length slots.
