Where did you hear this?
The best I can say is that I would imagine a lot of Android devs (and ios too) are probably eyeing up WP8. If it starts to gain traction expect to see the games flow in. Right now it's not worth porting, but at the same time, leave it too long and the market will be as saturated as the other OS. If they're smart, they'll jump on board sooner rather than later.
EDIT: Actually you might be getting confused with Windows 8 rather than Windows Phone 8. I did hear recently that BlueStacks was coming to WinRT which would allow many android apps to be played on a Surface. Maybe that's what you're thinking of?
