or better yet, don't buy anything at all. i have a huge backlog and i know the games i didn't buy this black friday will even be cheaper next year when i finish my backlog.
You know, I tend to agree with you but I'm not so sure this is true anymore with certain games. It's clear the industry is moving away from physical releases, and the numbers back that up. 30-40% of games sales are digital now, and that percentage is only going to keep rising. You have to think the incentive for publishers to reprint games is starting to wane.
I'm certainly not saying physical sales are going away completely any time soon, but I increasingly am of the mind that certain games -- once gone -- are in fact gone. There will always be eBay and resellers but whether that means prices really drop all that much remains to be seen.
Your comment was definitely true with the PS3/360 generation (I've picked up many titles I missed or were mildly curious about at mostly awesome or reasonable prices). Again, not sure the same will be true this time. I can definitely think of some games that will be hard to fid new, and I'm inclined to get those now.
