they abandoned their old trademark for until dawn and made a new one. also since reveal we havent learned a thing about it, its clear this game will be "reintroduced" in a way. so they are probably treating it as a new announcement. 

 God knows it had plenty of dev time

#excited, even if I hate hashtags

Hm, I personally took the March 31st placeholder date for Bloodborne on the PS store as a sign that that is planned for the first quarter, so maybe Until Dawn is for April/May.

Anyway I'm interested in what they've done to the game, I just rewatched the old trailer and really doesn't look very good, but who knows how it looks now. PS4, no more Move (that's just a guess but a pretty sensible one I'd say) and Sony feels that it's worth teasing it before Gamescom? Color me intrigued.

Sorry I can't see them teasing a game that's already been revealed, not a first party studio & not a major studio. This is 100% a new game, I mean why would they tease until dawn with a snow flake, hell it could even be a reference to ICE team and they're gonna show off ICE teams latest work at GC.
Also, until dawn is likely gonna be advertised as a morpheus game, and I can't see morpheus sub-exclusive games getting cryptic trailers like this.
100% a new game/ip

Frozen: Elsa's Revenge Ps4 exclusive confirmed

I think the large majority of people had already forgotten that this ever existed, so I think it doesn't really matter that it was already revealed. They might be teasing it because they want this to be something major, I guess the game has been reworked quite a lot since its first reveal and Sony might want to spark new interest in it. And the cover of the game involved snow, so that would explain the snowflake teaser.

Another possible explanation could be that we'll get a new teaser every day now up to Gamescom, so maybe that's just the first.

Until Dawn is set in a ski lodge on Mount Washington, hence the snowflake. And there's blood on the snowflake which makes sense since the characters are hunted by a serial killer.

The game in its current form has never actually been revealed. I think the game experienced many changes since its annoucement. From PS3 to PS4 and maybe higher production values considering the interest following the initial annoucement. That's why a re-reveal is appropriate.

The same will happen to The Last Guardian. I expect many changes from what we originally saw.

Looks like numbers if you pause the clip at 0.05
I'm probably just looking too much into it I always do with teasers

Yep. Definitely a good sign. Part of me still wants a surprise from GG, though.
