The PlayStation 4 and Xbox One games released so far haven't come close to taking full advantage of those systems' power. That's according to Strauss Zelnick, the CEO of Rockstar and 2K Games parent company Take-Two Interactive, who said during a recent presentation that the best is yet to come.

"We have yet to see entirely what the technology can allow," Zelnick said during the 43rd Annual Technology, Media & Telecom Conference this week in New York City. "We've had a couple releases for new-gen, but I don't think we remotely have seen what can be done, and that's super exciting. And that speaks to many of our titles; hopefully all of our titles, ultimately."

Zelnick's comments follow those from PlayStation president Andrew House, who said earlier this week that he's optimistic that E3 2015 next month will deliver games that take fuller advantage of the new consoles.

"I think it will be a show where we see the next generation of hardware really start to deliver great content and experiences that, if not take full advantage of the platform, take a lot more advantage than we've seen before," he said at the time.

The most high-profile of Take-Two's current-generation releases thus far was Grand Theft Auto V. This comes with something of an asterisk, however, as the game is an updated version of a last-generation title, albeit with some major new features and changes.

Take-Two's other current-generation titles include games from its 2K Games and 2K Sports labels such as Borderlands: The Handsome Collection, NBA 2K15, WWE 2K15, and Evolve.

Looking ahead, Take-Two has a number of current-generation games in the pipeline, including NBA 2K16, WWE 2K16, Battleborn, Borderlands 3, and possibly the mysterious "Advent" project.
