I don't think it will have any effect on gaming sales.
As previously stated, people play games to get away from the real world. This allows them to do that.
I predict that nothing will change. If that's the case, then anything expensive will not be bought. TVs, Cell Phones, iPods, etc.
People will cut back on the excess like eating out, and driving in excess, they won't let go of their ways of escaping the real world.
