isn't that what fans wanted? i mean a lot of people were asking for a "more open" uncharted in the next gen!
Uncharted was linear because the lack of RAM on PS3(it wasn't a good console for open world games).
It's the natural progression/evolution of this kind of game.Besides i don't the game will be a sandbox or something.It's just that,with 8GB of GDDR5 you can have a linear game with a bigger scope.
I for one only wanted more open/less linear levels. I like the format of uncharted games, I would much rather travel to several different exotic locations around the world than be stuck on one island (even if it is huge and varied).
With that being said I will still play this and will probably still love it.
