While we're waiting, SteamOS sale just started on Steam store: http://store.steampowered.com/sale/steamos_sale
HTC's Very Immersive Visual Experience is more impressive for its motion tracking than its display technology Vlad Savov
Verge just published their article about Vive VR: http://www.theverge.com/2015/3/4/8146523/htc-vive-valve-vr-headset-hands-on-preview
Another hands on article from Engadget: http://www.engadget.com/2015/03/04/htc-vive-hands-on/
Yes one of the Steam VR experiences is a short new demo set in Aperture Science. It's incredible.

I followed up to be absolutely clear, asking, "The demo being shown does not represent a prototype or indicate any plan for a new Portal?" Lombardi replied, "Correct. Just a demo." So no, this isn't Portal 3. It's just a tech demo until we know more—and I suspect Valve is just having fun with some existing art. Tyler Wilde on PCGamer

Valve's Portal / Aperture Science VR demo has me in love with Vive. I just don't think I'll ever be able to afford it http://t.co/plEHLkfMHW

Valve's virtual reality headset is great, but its controllers are the real story http://t.co/wZJZwz2Uba pic.twitter.com/X9kQPXoROK

Interesting change on http://store.steampowered.com/universe, Valve swapped ‘The Steam Universe is expanding’ for ‘PC gaming is expanding’.
The Vive's wands are controllers "equipped with little plastic hats." Valve won't rest until everything has a hat. http://t.co/hK5pHpiY6t

Everyone I've talked to at GDC who has seen multiple VR demos from various companies likes Valve's experience best.

Valve's VR Lighthouse technology is probably the most significant tech-step revealed at GDC. It's a simple idea based on existing ones.
— Erlend Wollan (@Wollan) March 4, 2015
Lighthouse dots the environment with IR dots. And the headset and controllers do inside-out tracking against these. And it works wonders.

We've used Valve's Vive VR headset and it's better than the Oculus Rift. Here's why - http://t.co/vwz4rubKTH pic.twitter.com/EOtY3kg0t5

The Steam controller feels more mouse than gamepad, and the right touchpad is genuinely hard to use as a stand-in for an analog stick.

I’m heading off for bed now, sorry that updates to the liveblog and Twitter will pause for a few hours until another SteamDB admin can fill in; it looks like ValveTime will have some updates of the upcoming VR talk, so do follow them.
The folks at Road to VR did a pretty awesome liveblog of Valve's "Advanced VR Rendering" panel. Check it out!
