For the built in streaming to local devices, a link: http://www.youtube.com/watch?v=Apv8aJqhANM ‘Gabe Newell of Valve Talks about Miracast’

Also regarding the streaming, https://github.com/SteamRE/open-steamworks/blob/master/Open%20Steamworks/ISteamStreamLauncher001.h

I think the following 3 are to come together (hopefully in the form of 1 of those news);

The SteamBox + TL;DR their own version of Ubuntu + A Steam controller

Also Newell has spoken in the past about the following, which surely will be part of Steambox's strategy:

Built-in streaming from desktop to other devices.

Having that into account, it leaves one extra 'spot' for a game announcement, and L4D 3 and Portal 3 have been rumoured recently.

Sadly, even in our most optimistic ideas, the f****g announcement of Half-Life 3 (or 2, EP 3, or whatever) seems far. :(

But hey, the above could be amazing.

Probably we will see Source Engine 2

Well, I'll bet on three things: a Steambox for livingroom and a kind of SteamOS of course a "Steam Pocket" who's a Steambox but basically designed like a Playstation Vita.

Why a Steam Pocket? since everybody can already build is own Steambox with Windows, I dont think many gamers will follow Valve in his crusade for Linux. Like this it's going right on the wall. the great lack of pc gaming is the non-ability to purpose a pocket experience. *the only way to get pocket version of games are: get them on ios/android (lack of buttons) or 3ds/vita (months to get a port).

With a Steam Pocket, you could play every game you want if it get a Linux port, and more with local streaming, cloud gaming, Wine, and non-Steam apps (drm-free, others gaming services and emulators).

Also, no games announcements today, or not in the "Big three" announcements.

Was my two cents, have a good day!

It is without any doubt a surprise.

My body is ready. Valve will change the industry, again.

They will announce the Steam Box for sure. And maybe they're own Ubuntu flavor.

Didn't even notice that you had a blog. I must donate to this thing - it's a great resource, even if it is equivalent to the bloke who runs around telling people that someone has arranged a surprise party for them.

Pulling stuff out of my arse, it'll all be announcements about the Steam Box (or whatever the official name will be) - today will be some general information, specs and a pic of a prototype, next one will be about the controller..and then the third about the software and the specifics about how things will work.

Steambox, L4D3, and one more thing (probably streaming).

I think the other two announcements to follow ought to be more Steam specific like this one that just came live instead of [insert game name here], unless that [insert game name here] is relative to the expansion of Steam universe, such as it will be a open quote playing with others close quote focused game hence having the ability to play outside of personal space is highly useful in that regard.
