Until I cleaned up my signature recently I still had the bets linked (I link long term stuff in my sig, so that I don't forget about it) with two guys, that seriously were betting PS3 would easily outsell Wii. And this weren't early lifecycle bets, at the time of the bets Wii was already above 100M and PS4 was near launch. So people just believe into ridiculous stuff. Because it fits their worldview or whatever.
