I don't think this is happening but it'd be cool if they did.

I doubt ND could do it alone (not while the majority of it is working on UC4), but if they outsourced the hell of out it, a la MCC, it could definitely be finished in time for the holidays.

Would be interesting to see how well done the remaster of each title would be though. The MCC suffered from more performance instability than you'd have expected (primarily in H1A, Halo 4, and especially with split screen), which i expect was the result of the outsourced studios and i343 working on a very strict deadline. With Uncharted there would be 1 less game to deal with, but each would be more of a pain to port (bless ye Cell, slayer of programming hopes).

I except an uncharted trilogy with uncharted 4 demo

Unless they're remaking Motorstorm 1-3 such statements aren't cool.

Most probably. And Bluepoint (god of war collection, metal gear HD collection and ICO/collossus PS3 port) is also probably doing the job:

They are recruiting currently:
http://bluepointgames.com/employment-opportunities/vfx-artist-contract/

"Help us remaster a highly-acclaimed franchise on a current generation console."
"The work is expected to take approximately 6 months"
"Create higher quality texture maps from lower-resolution source"

This is on their website since 1 year and a half ago:

"We are currently bringing a Sony classic to current game systems"

What games do you think they are porting since their last game (Titanfall X360) almost one year ago? What port do you think would need 2 years? surely not only one game...

That's great because they are the best in the porting business (we have never seen so good ports from a third party company before Bluepoint): Metal gear solid HD collection, God of war collection, both compilations and great ports of the original version running in HD and solid 60fps framerate.

On some levels, Titanfall on X360 (600p 2xMSAA) runs even better than on XB1 (792p 2xMSAA)!

I hope so.

I don't think so, especially if its supposed to be being developed by naughty dog. I expect an uncharted collection with 1-4 by December next year though.

It will be big for the hardcore fans and 360 converters. As big as uncharted 4? Absolutely not.

Would really appreciate it!

It would be a great idea. Hopefully this type of movement can inspire more Remastwrs to inude multiple games
