Prediction for The PS4's Lineup.

[forevercloud3000]

Well first off, I highly doubt Sony OR MS are releasing next gen systems in 2013 anymore. I think they see WiiU as a console playing catch up to this gen and a intermidiate for next, a non factor for what they do. They might be shown in 2013 but they will not release till 2014. This is almost cemented in the fact Sony is releasing such big name IPs next year. Not to mention this gen is expensive enough, Sony and MS could use to drag this one out longer.

Now when it finally does release(Spring or Fall 2014) it will boast an even stronger lineup than consoles in the past.
-Killzone 4 is an almost sure bet for PS4 launch. They have not put out a game for some time now and it would be too late to announce one for PS3. They are definitely working on something and Sony knows they are very good for showcasing their system's power.

-Sucker Punch: also a tad MIA of late but admit to be working with Sony, I expect inFamous 3, as opposed to a new IP, but this time the game might be more open. I see them using Cole as a mentor character now but allowing you to make your own hero/villain (or just another char all together). I see this game becoming even more Massive Open World and RPG like. Maybe even some online.

-Uncharted 4 might be a launch window as well, what better game could they use to sell the system? If not Uncharted than assuredly the Next Media Molecule game will be there.
