Erm 100% of Blizzard's revenue is generated by PC Gamers, so therefore I extrapolate from my dataset that 0% of gaming must be happening on other platforms.
Picking Activision or Ubisoft are bad examples as they primarily produce console games with PC as an afterthought. Fortunately they are not the only game manufacturers, nor are they representative of the gaming industry in general.
Activision Blizzard is a single company and the market leader. So yeah, it's very representative.
What I wrote are numbers released by the publishers themselves. Before you make a fool of yourself again: Better read what you post. The infographic says very clearly that the 2011 and 2012 numbers are predictions by a 3rd party source. The infographic onlycompares PC vs. consoles but ignores the entire mobile market (I just wrote that 5-7% revenue are PC games, not that the remaining ~95% are consoles). They are not actual data.
The infographic also explicitly includes browser games that are already Linux-compatible. Was there a rush of FarmVille players to Linux? No.
So if we include browser games in a discussion about AAA game publishers, fine: My argument was that Windows users have an irrational emotional attachment towards Windows and the installed base of PC Linux will not change via further availability of games, as the free Linux ports of id Software's and Epic's games -- and by your will also availability of browser games -- already proved.
To repeat myself: Linux is great and it's the main platform I use. I'm not bashing Linux. All I did was countering the claim that Steam on Linux will suddenly lead to a mass migration of Windows users to Linux.
We had AAA games on Linux in the past. It did not change a thing and Steam will not boost PC Linux from 1% installed base to a 30, 50,or 70% installed base. It just won't.
PC has a niche in MMORPGs and strategy games but the overall majority of revenue is generated on other platforms: Consoles and mobiles (iOS, Android, NDS,...).
Valve's ambitions on Linux have nothing to do with PCs. Valve wants Steam with its big picture mode to run on "livingroom hardware" (=smart TVs) with Linux as option to run on them. See http://www.gametrailers.com/full-episodes/ncis3o/gt-tv-valve (after 3min) for an interview with Valve's boss who confirms that. The Valve games announced for Linux (TF2, L4D2, and Portal) are not high-end games like Battlefield2. Smart TVs capable of Full HD playback are powerful enough to run them.
