Very well said budrojr, especially about just simply waiting for the 20% off price 2 months after release. There's always another game to play in the meantime.
I would add one other factor for consoles. The current AAA games kinda all look the same now (often using the Unreal engine for one thing) so there's little to marvel at when a new AAA game comes out. If anything, games look and play worse these days on the PS3 (i.e. Skyrim). So for console gamers, there more and more reason to be less and less excited about new games that cost 60 bucks.
