Wasn't Reader used in Daredevil fairly recently?
Inferno is a member of Marvel Rising, so he's still around. Not as successful as Moon Girl or Ms. Marvel, but not forgotten. The rest though have been reduced to occasional cameos (Iso was in Rising's just finished second comic volume too, but only because Morgan le Fay attacked New Attilan).
And what's with those Hulk scans? Machine Man guesting? He's hardly forgotten, he's currently being used in Iron Man!
