I kind of like that they have 2 dev teams. One team can focus on an existing franchise like Uncharted / Jak and the other can explore new IP ideas like The Last of Us. If anything though I would like to see Uncharted 4 as a launch title.

UC4 to sell the system

Jak 4 or a new IP.

Uncharted 4. They're already doing The Last of Us. After these games, then they should consider exploring new IPs.

My heart says Jak 4 but the Uncharted series is just too popular to not put out Uncharted 4.

I like Uncharted, but rather see something new. However, the Last of US is something new so I don't know if we will see another new IP from Naughty Dog this soon.

New IP. No doubt.

Uncharted 4. Just to see what ND can do with the new hardware. However I would like them to be a bit more creative with U4 in terms of gameplay...perhaps open up the game a bit more to spice it up.

U4 with the exact same formula as U3, U2, and U1 seems a bit outdated now. All the greatest franchises keep things fresh while maintaining the feel of the franchise. If they can pull that off together with the new hardware then i say keep the coming.

After U4 id like a new franchise.

UC4 <333333333333

Id buy a PS4 in a heartbeat

then you will play that game for like 44 times straight to set a new world record :P
