Rockstar currently working on “next version of a famous IP”

Once Rockstar has released Grand Theft Auto V, the company has to focus its resources in a new project, a new million seller. CVs are insidious for companies, sometimes their workers have unveiled announced games or have dropped a hint about something that the company is making secretly. This time, one employee from Rockstar had upload to the Internet this CV:

Hence, Rockstar should be working on a new game, but what game? If we consider the description given by the author of that CV, It should be a famous IP. I would appreciate as famous GTA, Red Dead, Max Payne and L.A Noire. If I not mistaken it could be any game between those IPs.

Thanks, VG24/7.
