I think that you may be correct that R* only released GTA V for PS4xbonePC and DLC updates in FY2015. But they might surprise us with something additional. But that plus NBA 2K15, WWE 2K14, Evolve, and some other DLC may be enough for a profitable year thus allowing other projects to be cooked for longer.
I wonder if a Rockstar Team should put out a WWE game. That could be interesting.
I agree as to being profitable, which is what Z has guided for to date for FY15 but don't think R* will surprise me. Average estimates are $1.36B in revs with $1.01 Non-GAAP EPS, and I just don't see both those being reached on the releases disclosed to date plus GTA V for PS4xbonePC and DLC. I could be underestimating those, but right now I feel more will be required.
I think this year best we can hope for is GTA for PC/PS4/XBONE and some DLC. Considering they announce major games at least a year in advance we cant hope for RDR2 really. Next May will be 5 years since release of RDR so that would be my guess for release window.
