During Take-Two's earnings call, the company mentioned that Rockstar Games is working on some projects and will have more news "soon."
Specifically, it said, "Rockstar Games also is hard at work on some exciting future projects that will be revealed soon." That's pretty vague, but at least there's some news on the horizon.
There have been rumours circulating about what Rockstar Games is currently working on. A sequel to Bully has been rumoured for quite some time, as has a new title in the Red Dead Redemption series.
Meanwhile, Take-Two revealed that GTA Online has been performing well, particularly when it comes to things like DLC and virtual currency.
So nothing to get excited about just yet, but hopefully Rockstar's "soon" isn't too far away.
