I honestly disagree. Despite the larger 'media blasting' of games like Halo or Gears of War, there's millions upon millions of PC gamers versus console gamers. Let's take it by the numbers: 50 million XBox 360s, 42 million PS3s, and about 76 million Wiis. Call it about 150 million overall active console gamers worldwide to account for older systems and overlap between platform ownership?
StarCraft 1 or 2. Look at the Asian competitive gaming market, it's huge for these and other RTS/pseudo-RTS games like mobile-artillery-fire sorts as well. Those are around 15-20 million active gamers depending on which news report you look at in the last year, some even higher. I'll go with 15.
CounterStrike and Team Fortress 2. I'm unable to find accurate stats for these, so I'll count them at 0, but mentioned here.
Hell, even Minecraft. 1-mil copies sold right there, at least 500k of those actively playing every day from when the stats page worked a couple weeks ago; they're mid-migration to a fully cloud-based web interface, so the stats-tracking code isn't operational at the moment).
Just from that handful of PC games, in a single day, there's roughly a sixth of the entire sold working worldwide console game population accounted for. One out of six, without delving deeply into stats, just nailing the highlights.
And that's not even touching on things like PopCap games that sell well, or all the various niche markets below the size or visibility of Minecraft. Or how many owners of consoles are actually active on gaming on a daily basis.
So, no, Windows PC gamers are not a minority compared to Console gamers at all. And that doesn't even touch on the number of companies supporting Intel Mac gaming now since Steam started the charge. Or even cross-platform and well-liked games that have millions of downloads for their niche market like rRootage for SCHMUP players, or the millions and millions of daily gamers visiting sites like ArmorGames or Kongregate. Or hell... the grandparents playing Solitaire on their Windows PC instead of shuffling a physical deck of cards because their arthritis has gotten too bad. That's still PC gaming too instead of playing it on a console.
