Am I just not remembering old releases of consoles? But, hear me out. Madden releases, it is supposed to stay relevant at least until lat Jan-early Feb, with updates and collections and such. But they would really release a game, release a new console, console isn't (immediately) backwards compatible, and then what? Have you buy a second copy of the same game?
Or you can buy a copy of said game for one console, and use it for that. It's not that difficult. You don't have to get rid of your current console, and rush headlong into GameStop to trade it in for a pittance. You can keep it.
