My list at the moment:

Civilisations Rise and Fall - mercifully rescued by Midway for a 2006 release after their developers went under. More fun with the ancients!

Commandos Strike Force Very tactical WWII squad FPS/RPG mix which is more like Hidden and Dangerous mixed with a bit of COD, but a lot more intelligent than COD!

Company of Heroes - Looks to be the next generation for WWII RTS graphically, but no idea what the gameplay will be like yet.

WWII RTS - If it ever comes out. Likely to be the most historically accurate WWII tank battle RTS of 2006

Battlestations Midway - WWII RTS set in the Pacific theatre. I would get it just for the naval battles which look superb close up.
