Rumor or not, I'm not really that surprised. Today, gaming is all about content. Content providers want to be able to reach all users. For the past decades, this meant releasing and porting their games to multiple platforms. It increases the costs and often causes glitches and bugs (GTA 4 anyone?). With the convergence we witness today, it's easy to see the future lies in browsers and the cloud.
I know my opinion angers you and you're one second away to thumbing me down, but think about it : is it really a bad thing? If tomorrow's games are able to fully utilize the hardware you have, regardless of the "window" in which the game is played, isn't it a win situation? The only losers in this are the consoles makers, which rely on game exlusivities to sell their console. They'll have to switch their strategy to making attractive but open consoles and portable devices. Maybe Sony got that. Microsoft is pretty safe with their next Windows 8 console. What about Nintendo?
You may think I'm crazy, but look into your heart. You know my words to be true! 😉
