Yeah after October 26th which is when their VR game releases, Take 2 has nothing publicly revealed on the slate going into their fiscal Q4 2017 or anything for next year that's been announced. Their investors call is November 2nd so it'll be interesting to see what happens between now and then.
Quick bit of history but in 2011 GTAV was announced on October 25th. A week later the first trailer debuted on November 2nd and Take 2's investors call was November 8th. So the idea and rumor is that if there was ever a time Rockstar would announce anything this year before the end of October we'll hopefully hear something.
Even if they don't announce anything, we will know if there is a Rockstar AAA game coming this year when T2 reveal its earning forecast for its next fiscal year, like happened when they implicitly revealed GTA V for PS4/X1/PC, a few months before it was announced at E3 2014
