I reckon that so far consoles have been like 5-6 years apart for each console but if you think about the current consoles they might last a while! It might take a while to improve current graphics and memory and overall power. So far the most innovative ideas have been ninty with the wii and ds and portable gaming and each are timeless classics but with sony and microsoft where is the innovation? Power and graphics isnt everything yes graphics look good and power is good but those are nothing if they dont entertain you! where nintendo lack in power they make up for in fun easily i mean i dont see sony coming up with a game which involves you running around swinging your arms about. This gen could be round for quite a while!
