Possibly, but not for too long I think. The moment one shop starts selling them for £40 to shift more games, the others will follow suit. I think it'll settle at £40 a game inside a couple of months.
Yeah i think they will drop just like this Gen games started at £50 and i dont recall buying a game for more than £35 in years even the big games like FIFA and COD's just a waiting game. That said i'll still pay more when they launch because i cant wait lol.
