Ever since I got back into collecting in 2000, every year was supposed to be the year that DC keys started to catch up to Marvel keys.

It feels like the opposite has happened (especially in the last few years), and the gap has widened considerably...

I remember hearing the same thing in the 90s...

Superman and Batman will always do well but outside of those, their mid tiers don't even compare to Marvel's, as far as popularity and sales.
