A new generation will kill the consoles.
The technical capabilities have already far outstripped what practical considerations could reasonably allow.
In the last 10 years the cost of developing a game has gone from 1-2 Million to 20-100 Million.
Square-Enix themselves said they can't remake FF7 to the "Modern Standard" because it would cost to much.
Think about that for a moment; they can not duplicate an experience they managed 15 years ago.
Length, depth, width, and game-play have all been sacrificed, so that technical capabilities can be effectively utilized.
The industry feels they NEED to stay on the technical curve, lest people stop buying there games.
They think they're in a Red Queens race, but really they're just blindfolded and running off the edge of a cliff.
