I saw this too, it definitely seemed to capture the spirit of Halo, hopefully it'll translate into a good RTS.
Another one that looks like it has potential is Tom Clancy's Endwar, it's supposed to have some really good voice commands to control anything in the game, if they nail that right, it could turn out better than mouse + keyboard for RTS, but that's a pretty big if.
