I disagree...
Yes, there are less PC games coming to market, but the quality of the ones that do is much better. Plus computer games are continually improving because of better, faster hardware being available. Console games must run on a static platform for 2 years or more with little or not ability to upgrade.
Yes, console games are idiot proof and online play is picking up. But, it is nowhere near the immersive experience that it is on a computer.
Console games are more of a family entertainment device. One or more people can participate and watch at the same time. You don't get that with computers. Whereas, computer games are more of a singular entertainment device. I don't see a bunch of guys crowding around a computer watching their friend play some counter-strike.
The market is always shifting. I remember when games for the Commodore 64 outnumbered all the games for the Attari and whatever the other console was at the time. Games have benn the catalyst to pushing the computer platform and will remain so for some time.
