This discovery comes from Doctre81 (who I think is also on GAF), and most of the key info comes from a Linkedin profile.

I was reluctant to share the profile link, however the video already showed it alongside the url, and I personally spoke with Stump for advice on how to share it, over concern about exposing the employee, and got clearance to do so because of the above.
Doc seems to think it is Return to Arkham (which is Asylum and City in UE4).
To me the wording implies a singular game (all the games in the thread title are collections), so it's possibly an unannounced multiplat game? No way it's exclusive (as a Virtuos port I mean)... right?
I'd personally love a Japanese game, even Final Fantasy X and X-2 over a western game, hell Batman wasn't received well was it, HELL, did it even come out?!
Edit: Just made an article of it if you feel like checking that out also. :P
