we should make some actual predictions, lets see who guesses the closest !
one of the three orbs is almost certainly the steambox console thing, but the other two?
my bet would be some kind of input device/controller with the biometric features valve has mentioned it was exploring before.
Also perhaps we will see some new tools for developing specifically for their new linux based steam platform, and or perhaps source2 which clearly has been designed with linux in mind.....
However its very unlikely that source 2 is being revealed just yet as id imagine they would want to tie it in with a game reveal.
Though if valve are really serious in breaking into the living room space/console market then it will need some upcoming titles behind its hardware. Obviously they have an extensive catalog of existing steam games but only a small portion actually run on linux and i cant imagine they will release a console with a tiny library of games. Im sure that valve will be working on at least one game (l4d3 perhaps) that will be a launch title for their console.
Probably though this game will be revealed separately , and probably in 2014. What do you guys think?
