I think it will be a challenge definitely. Valve have a cult following and that will help if they make their own games exclusive.

One part that could side with them are the purists who can't accept new control methods. I think it can have a bit of success if they sell at profit.

That is another point. If they develop their exclusives for it, they will lose quite a bit of revenue. They won't stop making HalfLife for the PC, that is for sure. But even cutting the Xbox 360 / PS3 version would mean 50% less revenue. Gabe even said that Left 4 Dead did better on consoles (360) than on PC, Portal made more money on PC though.
