One word, PRINT
I've recently been revisiting a lot of my images and printing again and you know what, 16mp is awesome even at 17x22in (albeit square or 4:3 vs 3:2), and that pretty much covers all of my gear with the exception of my MF gear.
Do I see the difference at 24in wide off my Z3200 when shooting 60mp or 36mp - sure I do. Do I see it at 17x22? In reality I can't say that I do when the images are all well prepared from 16mp.
Thoughts? Am I smoking crack or just have low standards? I don't think so but I'm intrigued by the the thoughts of others here.
Ps. Not selling off the big gear anytime soon, if ever.
