Hurt sales? It IS gonna hurt sales, no doubt about it.
If this happens, it's gonna piss a LOT of people off, myself included.
I am NOT about to go down to Wal-Mart, Target, GameCrazy, or where the hell ever and pay $60 for a game. No way.
If this price increase occurs, I probably won't buy very many brand-new games, unless they're greatest hits titles, or whatever. Or I'll buy used games, since they're generally cheaper.
