I don't think the problem is the long hours, but the repetitiveness of the games... If a 50h game as a main story and the game is basically the same (like shooting, dying and trying again) they'll get tired pretty soon...
Now, if they are going to start to do games with 10/20h only, i'll start to banish games for my life... Paying 60€ for a game that lasts a day isn't my kind of thing...
