They are too busy on projects that will actually make lots and lots of money- (at least that is the theory for TWI)- like KF2 for PS4 or Xbox. I wonder if they have the ability to pull off KF2 for UE4- there will be lot of competitors out there that they will be up against. I also am starting to believe that TWI merely put out RS to enhance their resume and look like they have been actually up to something- one needs to have a fairly good looking corporate resume (or at least appear to be busy) when approaching the console commanding heights to get onboard the early dev inner track and access.
