I do hope that Sony kills off some series, reboot, or pass it on to another dev.
Killzone - kill it off or reboot (I know some people love the series, but the game just needs a fresh start. I WOULD rather play as a Helghast than a ISA.)
Uncharted - let ND A team do a new IP before doing another Uncharted (Having more IPs in the beginning of a new cycle is always good.)
LBP - Just better on the Vita. New IP from MM would be good.
Motorstorm - kill it off
InFamous - I imagine SP are working on something new and this series is on hold or passed to another dev.
I wouldn't be surprised if one of the new studios is making a WRPG. I do wonder why Sony haven't done a new Ape Escape game and would rather have it than Ratchet.
Kill of Killzone? Reboot?
Killzone has so much more to go. 3 was nonsense IMO, but they can repeat the Killzone 2 hype next gen. All they have to do is nail the story, bring back Killzone 2 elements over Killzone 3, and flesh out MP and co-op. So much potential that GG fails to capitalize on that has resulted in the series quick waning.
As much as I loved K2's MP, there was a lot they could improve on. Killzone 3 was one huge step to the side, and one step back. If they can properly improve on the MP, I can see a lot of people sticking around. Battlefield did a fantastic job of making me believe squad based MP can work over arena-type shooters on consoles.
I fully expect a Killzone 4 launch title.
I'd like Uncharted to take a break, and expect a new IP from ND. I think the MP has a lot of juice left if it goes back to UC2-style MP
I'd hope Sony has the sense to reboot SOCOM as a launch title
After Tearaway, I want a new PS4 IP from Mm, and LBP 3D Land a la Super Mario/Sonic Adventure. Hopefully by then enough titles would be developing for the VITA that Mm can focus on PS4.
