Honestly, I think it's less a point of contention and more a matter of the few people who have the ability to change the forum descriptions not being around and not caring to update them. Personally, I see the Modern Gaming section for discussing current gen stuff and Classic Gaming for everything older. In practically, that's usually how it boils down. Now, do I personally see, say, the PS3 as "classic" or "retro"? That's a different matter, but it's not of great concern of me which systems "deserve" these titles and which don't, anyway. I find that argument often comes down to elitism.
