Most times next gen is used it's meant to assume current gen. The phrase has transformed into something like Band-Aid, Scotch tape, and Kleenex. Those are brand names but most people use those words to describe the general item no matter who made it (I don't blow my nose with facial tissue I blow it with some Kleenex). Same with calling current games next gen. We've used it so many times and in so many situations that they are now synonymous. We need a new classification. :P

3DGS is a studio because (in THEORY) it contains all you need to make a game...modeler, world editor, script editor, language, etc. That's splitting hairs but it is what it is regardless of quality, features, etc.
