Does anyone know how much money you would make if your music got picked up for a video game?

My hubby just got signed with a descent record lable, and they want to put some of his electronica music on some video games coming out for playstations, xbox’s,ect.. They are also interested in doing a music video for one on his club remixes, does anyone have any idea how much money he will make doing this?
He just got signed and the contract is being dawn up, but they havent discussed money yet, we are just curious as this is happening so fast:-)

THEY EXACT FIGURE I DON’T KNOW BUT IT WILL DEFIANTLY BE ENOUGH TO HANDLE SOME BILL AND SO FORTH TELL HUBBY CONGRATULATIONS JOB WELL DONE.
