CyberConnect2 are the guys who have brought us the .hack games, as well as the Naruto fighters, in association with Bandai Namco. So yes, they may be a divisive game developer in terms of their reception, but they have a hardcore fan following. Enough of one to host their own event, actually.
They held one just recently- the “CC2 Summer Campaign 2014” talk event, where they revealed that they’re currently working on a major project.
This, of course, wouldn’t be the first time the developer has worked on original games, but unlike previous original releases, which were more like side hobby projects for them, this new release is, in their own words, supposed to be a ‘major new title.’
That is all that we know about it for now, though. As to what kind of a game it is, or what platform it is coming on, we have no clue or inkling whatsoever, although with TGS just around the corner, more information can’t be that far off.
