Looks actually cool.

Looks really nice, can't wait. ^.^

I don't understand what's going on at all on the first screenshot. Are vertical resolutions a thing in PC gaming now?

Regarding the second screenshot, I don't like that blue-ish hue but I'm kinda interested in that "comics" tab ("TV" tab can go fuck itself though).

It...it looks so...beautiful..

Um...

Mortal Combat X?
Forza Motorsport 5??
Halo 5: Guardians???
Comics????
and no Anime?????

WTF Gabe

I like what I see

time to opt-in beta.

To me leaking these images in the beta client seems more like a legit accident from someone tasked with coming up with Steam UI prototypes (or something) than it does a Vavle teasing an upcoming update. Would be nice with an overhaul of the UI but I'm not holding my breath for it anytime soon.

Concept art.

I didn't like the friend list on the upper right corner, like Origin. Lower right was much better.
