The game has been in development for quite some time, but I agree (early) 2016 seems like a more likely scenario than late 2015 due to uncharted 4, but don't fully rule out a december 2015 release yet, one can dream right.

PS4's gameplay screenshots of Shadow Of Mordor by me :

The guy from Capcom that makes Street Fighter, he always carries that small green toy figure around with him and he's said to be working on an unknown PS4 exclusive.

Shinobi said its not a 2015 game. and that guy has been freaking spot on about the game so far. 

thats interesting. maybe that game will be the game that makes people "rage"?

Who knows, the other (probably more likely) scenario is that he's there to talk about Deep Down. I totally forgot that he was the one that announced that game during the PS4 reveal.

damn, that game is such old news now. i totally forgot about it lol. it would be extremely boring if they talked about deep down, but then again, i expect the event to be mostly boring stuff so that fits with my expectations. 

Yeah and interestingly enough I just checked the source that did say a couple months ago that he was working on an unannounced PS4 project and that has been changed from  "201X unreleased title PS4 Producer" to "201X unreleased title TBD Producer", could be them just trying to hide something, but could also mean that the exclusivity doesn't exist anymore.

Yup, Shinobi even dropped a hint saying that some mechanics of the game are still in prototype stage. It looks like this is a huge project.

maybe, or maybe they are trying to hide it. i would really like to see shadow of the beast in the show, even though i doubt it, seems like it got canned.
