If PS3 continues to sell, lets say another 20M over 4 years to reach 100M LT, you can't pretend that it only sold 80M LT just because the new gen launched.
The console is still selling, it's still relevant because people are still buying it. If it outsells the Wii then it won the 7th gen. Sony put a lot more effort into the end of this gen to extend the life of the console and have an history of doing so.
