Motherboard makers not keen on Intel's G4x chipsets
 

The G41 does offer slightly better graphics than the G31, but in that particular market nobody really cares. The problem is that it has worse CPU compatibility, and it also seems to have lower memory and drive performance than the old G31.

What's more, things don't bode well for the G43 either. The G41 already features HDMI and it will get improved memory support, thus making the G43 rather pointless.
