On the desktop I use discrete graphics from that other company that isn't spelled with 3-letters, but I use good ol' fashioned 4500HD graphics on a core 2 notebook and they do pretty nicely with KDE. I even do HD audio + video out over HDMI to my TV and it works out of the box on a composited desktop.

My question to you is more related to future graphics. I know you can't go into detail about the capabilities of IB and Haswell, but I was wondering about: 1. If you can give any predictions about how Wayland will develop alongside Intel products in the future, and 2. If you have any idea about getting QuickSync support in the existing Sandy Bridge systems working under Linux (If QuickSync is unrelated to your work then I apologize for being off-topic).
