"Will Wright has said in interviews with GameSpot and IGN that they were aiming for the second half of 2007"
Maybe I will have a projector and a 360 by then
I strongly suspect that this will be a PC only title (at least at launch). Hopefully they will be able to work out a console controller friendly interface. Nothing would be worse than trying to play that with a clunky interface (the same as black & white or any other RTS for that matter).
Once it does ship for 360, you might want to pick some extra bulbs for that projector
A typical game might last more than 3000 hours!
Just my .02
