Hardware wont be the problem but the fact that there is only so much you can do as your budget/stuff allows
Games like Horizon, Uncharted 4, Bloodborne, Driveclub is the maximum you can get out of human beings lets be honest here, unless you want to have 1000 people working on a single game somewhere in china for even less pay and more work.
Its pretty likely that the next generation will have 60fps @4K at least as far as first party is concerned.
