Although I haven't thoroughly read the entire forum yet, the bits that I have read have actually been relatively un-flamey. People are at least attempting arguments, which are at least a step in the right direction.
As I continue following this thread, we'll see if my tempting fate will go unpunished
I have read several arguments against Bob's video, and they all follow one of two lines of thought:
1) Look at all of the great stuff coming out exclusively for the PC this year alone. How can you say that PC gaming is dead?
2) I have played both, and the consoles simply are not up to par.
These are actually fair arguments. However, they are both fatally flawed for a simple reason: these arguments only address the most immediate future for PC gaming. This video is addressing a long term change over a period of at least a few years, well beyond the current fiscal year.
If the last few years have convinced me of anything, it is this: the only genre that has *yet* to be proven doable on a console format is the RTS. Every other established genre, as well as genres that haven't been established on the PC and haven't even been created yet, has been put on the console to both critical and commercial acclaim.
The "decline" of the PC gaming platform is really a misnomer. "Evolution" is a much better word, because it regards the various platforms (Playstation, DS, PC, iPhone, etc.) not as separate entities, but as a continuum in the advancement of technology, specifically in regards to video games.
A few months ago, I built my first gaming PC. It is wonderful, and I enjoyed both the experience and the amazing results. However, it was not a simple process. I had to buy each part, educate myself as how to put them all together, and mess around with software and settings. Practically, not to mention financially, it simply makes more sense to invest in a console, or even limit gaming to technology you already use.
If you want a preview of the future, look at Japan. PC gaming is virtually non-existent there, because the data infrastructure is so advanced, and everyone has a futuristic cell phone.
In the relatively short term, there may be some things that suck. Certain PC-centric genres that can't make transitions to other platforms might die. And then technology will get better, to the point that the future equivalent of facebook will be able to support games that will make crysis look like it was rendered with crayons.
