Assuming this quote means what I think it means (that they're making f2p service games, and by "Valve" he means "Dota 2/TF2" and not Portal), this would line up with what Tim Sweeney has been implying for a few years now along with the shift away from things like Gears.
Polygon said:"We're building Fortnite, which is a bigger and way cooler game than we imagined," Sweeney said. "It started out as an internal game jam project at Epic and has grown over time. We have a combination of a great building game, an action-combat game and with some [light] elements of an MMO. We'll be saying more about that in the coming months."
Sweeney called Fortnite a game that will be shaped and improved over time in response to its players' feedback. It's also a game that represents something of a new direction for Epic.
"We're looking at the future of gaming from kind of a Valve or Riot point of view," Sweeney said, "[which is] making your games really accessible, being fair to customers and giving them a great value with a game that can be played for hundreds or thousands of hours.
Sweeney said a team of more than 90 at Epic are building Fortnite, which he praised as an "awesome, high-quality game," and that others at Epic are developing unannounced projects.
"We've gone through a long process of figuring out the games we're going to build at Epic worldwide in the future and we concluded that we weren't going to be building any more Gears of War," Sweeney said. "As much as we love the game, we're heading in a new direction.
"The core Gears values are really tied to being big event-based, single-player console games with awesome cover mechanics and other things that really didn't translate into the future approach we were taking with online games, and competitive and cooperative multiplayer. Because we weren't planning on building any more Gears games we were just going to let that sit on the shelf for a decade or more, in case it had any future value to us."

"We're working very close with Nvidia on new features and capabilities to bring things to the next level.
"We won't be announcing that [game] for a long time but we're continuing to be at the forefront [of graphics technology]."
