People have been more satisfied with the Xbox 360 than the PS3 so are less inclined to upgrade - one of Yusuf Mehdi's opinions on sales gap

This is funny seeing as how the PS3 is still selling at a high rate while the 360 has declined significantly, but the X1 sales are not impressive. everyone I know who had a 360 got a PS3 and have or will get a PS4 in the future, but not an X1. The last year for the 360 was terrible while the PS3 had one of its best years exclusive wise.
