Whats even more sad is that if the new consoles were on par with high end PC's, they would cost ALOT, so therefor Id say the new consoles will be midrange PC's whenever they release. They will age even faster than the PS3 and 360 did (keep in mind the current consoles have been old for awhile)
Unless they made snap in, plug play simplistic upgrades for future consoles. Then they wouldn't have to come out with a new system every "x" amount of years. The idea from Nintendo 64 with that red add in pack that made graphics look better supposedly...but using it as a example...certain games would have certain requirements just like a PC...consoles are for the simplicity, and comfort. Make it easy, portable still, but upgradable and upgrades would not require a install, just snap in and close the lid per se.
