I think John is well aware of his reputation. It's interesting that despite him being CEO and a coder, he's promoting this as the Tom and Brenda show.
One worry is that this studio has only a couple of facebook games under its belt (that I can tell): Ghost Recon Commander and Pettington Park. GRC got good reviews, and being a tactical game is at least similar to the isometric perspective classic party-based RPGs use.
It's interesting that Notch and Chris Avellone support this.
