"One might argue that consoles now have longer lifespans than ever, and so consumers may be put off by a new Steam Machine so soon after another." Stopped reading after that. Sony has even suggested shorter life-cycles. Why the heck does everyone have this misconception that they need to upgrade their PC's so darn often to play newer titles. This is flat out ignorance and WRONG!!! BTW consoles are already out of date, they were from day one. Nobody is put off by those hanging around holding back progress for 7+ years? HINT: Go to your games graphics options, turn them down to reasonable settings, or better yet current gen console specs and be amazed at the ability of your PC to run any game. Sigh.....
Sony can suggest whatever they want. Whether consumers will buy a new console every couple years is another story. I sure as heck won't. If anything, I think they'd just succeed in pushing people toward PC gaming. It's hardly a misconception. The only way what you're suggesting works is if you started out with settings
better than what you need. The best part about consoles is you don't have to worry about all the future proofing crap. (It's a pain in the ass--4 months ago people were recommending GTX 760, now it's 780s). Granted, all people who think a game's unplayable at anything less than 30 fps @ 1080p resolution are idiots. As for consoles "holding back progress for 7+ years," I think the problem is with people who think pretty graphics = good game. I think PC games would be better off it they weren't trying to constantly push the graphics envelope.
