Things are starting to turn around, though. Sony and MS have finally released consoles with 8GB ram
Uh yeah, quite some time ago now.
Only about a year ago. That's not very long.
At this point, cross-platform games are still releasing for the Xbox 360, which means they need to squeeze into half a gig.
The situation will change as the new consoles displace the old ones. But right now, games like Far Cry 4 and Battlefield:whatever are still worrying about the Xbox 360's tiny memory footprint.
