I agree with this - SMB3, for example, was pushing $20 for a loose cart before the classic. Now you can get it for $10-12 shipped. In general, NES prices are down, but I think the classics had a strong hand in killing collection desire.
The thing no one is talking about is console prices. NES and SNES console prices have plummeted. Before the classics, people on eBay would buy an NES for Christmas and let it collect dust. Now, they can buy an HDMI ready NES with the best games and... let it collect dust.
