Since Uncharted 3 is old, it's old but ND said that they will still update the game as long as people play it. I do not want them to just update stuff like new hats or colors or characters.
Uncharted 4 will be out for the PS4 most likely, so PS3 will be boring without Uncharted story lines. Here's my idea:
Make a new Uncharted story for Co-op. - ND can make 5 new chapters for co-op adventure.
Make a downloadable Uncharted game - Like Infamous Festival of Blood, we should have one for Uncharted. Maybe they can make the story out of the book that came out before U3. Uncharted: The Fourth Labyrinth. Then, I won't be sad that Uncharted's "campaign" left PS3.
Uncharted is famous for it's story and cutscenes, so what do you think?
Haters Love Me!
Not gonna happen, because Uncharted is a system seller.
Sony will want to sell more PS4 consoles...
And at this point in time its too late to bring out a downloadble SP story, they should find ways to extend the MP portion of the game bundle Maps, drop all items to 49 cents, release it as a separate downloadale game (which is imminent) and do a bunch of technical fixes.
TLOU is their main concern now Uncharted 3 is just a way for them to make money & milk the loyal UC3 fans.
