Yeah, they do seem to be touting it. They got a ton of mileage from their custom UE3, and Inj2 looked great, so I'm very curious if it's just a bullet point for the sake of it or if it's going to be a noticeable jump.
Shawn Kittelsen, the writer of the MKX comic confirmed he's not writing a new comic series since he's working on the actual story for MK11.
It's good to hear he's working on the MK11 story because his comic actually had a better grasp of the MK characters than the actual game. For example, Kotal is a much, much more interesting and likable character in the comic than he is in the the game.
I mean we don't actually know that.
No one at NRS has said anything about it yet.
All they have said so far is graphics engine, not game engine, if they wanted to be sleazy it could still be their UE3, but they remade the "graphics" engine part of it and that statement would technically be correct.
Disclaimer, I have no idea what I'm talking about.
