The 2019 Game Developer Conference kicks off tomorrow in San Francisco. We’re expecting some big reveals on the VR side this year, and Oculus appears to be teasing just that.

Facebook’s VR team just posted a blog outlining its plans for next week’s show. It’s largely comprised of stuff we already knew about, but there is one tiny tease. Along with new Rift and Quest demos, Oculus says it “may just have an announcement or two” up its sleeves.

No points for guessing what that might be teasing. On Friday we confirmed that Oculus plans to announce its upgraded Rift S headset at this year’s show. It’s thought that Rift S runs the same content as the original Oculus Rift but features improved optics and inside-out tracking. It’s rumored to also be coming in at a lower price than the original Rift, though this is all just speculation for now.

If Rift S is one announcement, though, could there be another big reveal in store? Perhaps something on the software side? We’ll have to wait and see.

Elsewhere we know that Oculus is going to debut a new game from Turtle Rock Studios at GDC. It’s said to be a little similar to a Zelda game. There are also going to be new demos for Asgard’s Wrath and Stormland. Attendees will be getting hands-on time with new, unannounced Oculus Quest demos, too.

And that’s just Oculus – we’re also expecting news from HTC and Valve next week. Best strap in, it’s going to be quite a ride.
