Hard to say, depends how hyped the game is. There's times when the Special/Deluxe Editions are not selling well and then they go on sale after release (Such as Dead Island 2, Street Fighter Steelbook Edition etc.) but then Lies of P sold out before release. My guess is that even if it sells out at GAME it will show up on eBay for less. Both FF7 Remake and FF XVI have gone on eBay post release for 25-50% cheaper than the pre-order. And pre-order bonuses such as extra steelbooks will flood the market as people will try to get back some money for buying the game.
