Just a wee heads up, there's an Ice Cream Sandwich flavoured ROM on the go based on CM7, Android 2.3.7 and LorDmods 8.0 BFS Kernel. From what I can tell, it uses the ICS Launcher available on the market and has the Clock, music app, the Market app and there's even the Galaxy Nexus boot animation linked in the thread too.
