This has been suggested forever and 3DO tried something similar without any success. Not to say somebody can't crack it but it'll be hard to sell a $600 dollar console that is no better than a $400 one, even if there is a slight difference in game prices. It'd save me money since I buy a lot of games but the average consumer only buys about 10 games for PS4/Xbox, they wouldn't really see a saving overall, plus sales already regularly let people get a game for less.
