I say Sony will release the Uncharted Trilogy Remaster in Summer 2015 followed by Uncharted 4 in holidays. It's possible for Horizon to come out in Winter 2015, too, but I think it'll be out in 2016. The Last Guardian will be out in Winter 2016 at the earliest and while this is 2 years later, I still think that it is too optimistic.

I just don't see Naughty Dog having been fine tuning all 3 Uncharted's while finishing u4 after Amy's departure. I think a Uncharted

 Collection is coming, but I think after U4. Hell if I nail this Summer prediction. I can see the collection releasing durin the holiday 2015 with Game of the Year edition of Uncharted 4 with it. 

I agree with others who say a Uncharted collection will hit stores before UCIV. Besides it'll move a lot more consoles in the holiday season.

I initially thought this for a while as well. Then it hit. That Naughty Dog lost its game U4 game directors and some things got reworked this probably stalled any UCollection work. Which I don't believe was being worked on during TLOU Remaster. Also, I don't think the UCollection will just be a 60fps upres like TLOU.. I think ND will remaster it in U4'engine and include next gem gameplay mechanics in the previous 3 as well. THATS why I believe it's coming after and not before. In a perfect world all that would come before but I don't think it will and because of of those factors I see U4 coming out earlier than expected. 

Hmm, I don't think a remaster would take them that long tbh but you make a good point. ND stated they were working on two other projects (not including UCIV or TLoU) so maybe UC Collection would be one of them? Or Sony could get outsource another developer to do it. 

I don't know if there is going to be a collection, but I fully expect UC4 to Sony's big holiday game. As for Horizon, I don't think we'll see that until 2016.

Bold indeed. Could happen who knows.

Can we just go back to calling it Trico? It's a better name and has just as much chance of being released.

If this is truly Drake's last outing his collection will be a complete overhaul inU4's engine. ND hasn't had the time to do that. Drake will go out in style.

The Last Guardian is Schrödinger's Video Game. It both exists and does not exist simultaneously. But I won't believe it's real until I see the title screen on my TV. Maybe I won't even believe it until I've beaten it. Or, heck, all of that could have been a dream.

2015 seems really unlikely, either way.
