Activision (you know the guys who own Blizzard, the WoW guys which is the biggest MMO ever). For the last 5 years revenue from consoles has exceeded revenue from PC by 2:1 (that's PC game sales + online subscriptions combined). The PC contribution to CoD sales must be tiny compared to PS360.

EA revenue, as already mentioned, is roughly 25% from PC. Less than half the revenue from consoles, less than half even the revenue from just PS3 and 360.

Ubisoft PC share of revenue has been max 15% since 2008. http://www.statista.com/statistics/269679/breakdown-of-ubisoft-sales-by-platform/

I dunno details for Valve, but they jumped on the console train last gen. And so did Bethesda, big time.

Follow the software money, rather than the hardware money, and consoles are still the revenue kings. Which suggests an actual PC gamer audience of maybe as little as 1/10th of that 900 million PC user base that the article in the OP claims.

AAA games still sell better on consoles...

I don't really get the OP...

 mmmm there are 1.5 billion windows pcs 91.8%!1.5 and 6.7 linux mac  marketshare...so lets say 1.7 billion overall pc s:P 

The big issue with that kind of research is that it sums up both AAA PC market (that we know it's small because of AAA software sales), F2P and MMO titles and casual games that we know will be cannibalized by smartphones like the Wii was.

The audience that consoles aim is the AAA: CoD, GTA and so on. This is too the audience of the core PC gamer, the guy with a decent GPU that plays the same kind of games. This part of PC gaming is smaller than the console market:
1 - Software sales are lower on PC (except on a few cases of games with a heavy PC appeal)
2 - Publishers usually don't launch all games to PC or do late launches like GTA. If it was a bigger market as you are saying, why wouldn't it be a priority?
3 - Most PC versions are console ports. Again, if it was a better market, why it isn't a priority?

I'm starting to get sick of all this discussion. The new console generation surely added a lot of fuel to the fire about PC vs. console. But I prefer to be more pragmatic about it. The publishers give priority to what gives money. This is basic business. A lot of people on the forums think publisher A hate company/platform B and won't go there. It's not like that.

With the PS2, Sony had a lot of 3rd party exclusives and timed exclusives (GTA!!), but when the screwed with the PS3, the X360 got a lot of 3rd party exclusives and right now all the 3rd parties are on both. There isn't a preference, the publishers simply migrated to what they tough that would dominate and them supported both better when Sony fixed part of their mistakes with the slim PS3 and the sales picked up.

Just look at the news today, Destiny is coming to PC in March 2015. 6 months later. We will know when and if the PC gaming market is bigger the day AAA games become PC timed exclusive or simply just launch only on PC.

This topic is ridiculous. Titles like COD, AC and other big games barely do Wii U numbers on PC. Most PC gamers play Candy Crush or maybe titles like WoW, LoL, Diablo and a few other key franchises. The market for those playing traditional console-type games is niche at best. The article talking about gaming hardware revenues was dubious at best.

PC gaming is fantastic, but it's split between the super hardcore crowd who will pay for premium visuals, like to MOD games, etc., and at the other extreme the super casual crowd who play only Bejeweled or Candy Crush. The bulk of gaming dollars, those customers who buy most of the COD's and Batmans released each year, are on consoles, by far.

yeah huge victory for ten thousands PC game companies who are generating more revenue than 3 console companies. Well done.

"The PC isn’t dying, it’s merely redefining its form factor"

Thats a part of the argument why PC gaming IS dying. no-ones cares if candy crush made a gazillion, whether you are on the PC side or the console side.

What does that have to do with anything? I didn't mention the total PC install base, just that the 900m figure is representative of something irrelevant to console gaming. Farmville or candy crush aren't exactly competing for market share with GTA5 :p

If we were talking purely about the PC market, then that 900m figure is likely a legitimate estimate. Gaming is a rather broad industry after all. The second you want to compare it to consoles though, you have to restrict your comparison to the parts of the PC market actually competing with them. 

A 900m install base isn't worth much when a much smaller install base of 180m HD consoles can dominate so frequently in with the software sales of major publishers. You'd almost think there were several parts of the PC market not part of the core industry :p Same with the console market, the "other" parts just make up a smaller portion.

lol.. good luck with that.  as far as I know, ps2 and og xbox emulation is still unreliable and buggy.  ps3 and 360 emulation are still in infant stages and remains to be seen if they'll ever truly be emulatable..  and yes, though ps4 and x1 share similar architecture to PCs.. it's going to be a long time before they ever get any game ps4/x1 working on a PC, if ever.  so, theorectically, you can possibly enjoy these ps4/x1 games 20 years later.. i'm sure that's going to impact these devs and their pockets by NOT making a retail version of games for PCs.

Emulators? Lol. I dont believe that some peoples ego is so big that they want to play all games at 4k. Will they buy legit games for those emulators? 99% change is no. It is pirates who hide under the shadow of very tiny legit owners talk about emulators. Emulators are a feast of pirates.

PC gamers get to play ANY game they desire = They get any thing to play. Is their birth right to do so? Nope. They are kind of snachers who like to bully everyone. Like a bully they think the world revolves aroud themselves.

Neither Dolphin nor PCSX2 have been perfected yet, and we don't have a PS3, 360, hell, we don't even have a 3DS emulator, but we have a PS4 emulator? Damn.
