Take-Two CEO Strauss Zelnick has dropped the greatest hint yet that a sequel to 2010 open-world hit Red Dead Redemption could be in the works.

Speaking during Take-Two's Q1 FY14 earnings results last night, Zelnick stated that the publisher's goal is "to try to create permanent franchises", before referencing BioShock, Borderlands and Red Dead.

"Our goal is to try to create permanent franchises," said Zelnick, "that's the unique goal in the industry.

"Our competitors do not see it that way. Our competitors' view is that our franchise will have a certain life, and at the end of that life, you move onto the next thing, so you better make hay while the sun shines. Our view is to the contrary. The best franchises are permanent franchises.

"Outside of our business you can look at James Bond, for example. And it's been our goal not just to preserve and grow the Grand Theft Auto franchise, but also to build other franchises that we think can be permanent, whether that's the Red Dead franchise or the Borderlands franchise or the BioShock franchise or others, Civilization, for example."

Take-Two, which owns Rockstar Games, has yet to announce a sequel to Red Dead Redemption, but previous comments from Rockstar have suggested a sequel may be in development.

Back in July last year, Rockstar asked fans to "stay tuned for further announcements about the future of the Red Dead series".

Red Dead Redemption sold 13 million copies within the first two years of release. Take-Two announced last night that BioShock Infinite and Borderlands 2 had each sold 4 million and 7 million units respectively.

Rockstar's next title, Grand Theft Auto 5, goes on sale on September 17.
