Am I the only one who thinks the absolute opposite, that the relevance of this generation is peaking at about 2010, probably even later?
Has it ever occurred to you that the PS3 does not even need to outsell the 360 on a monthly basis until after the sales of the 360 has peaked in order to outsell the 360 during its life time?
The PS3 seems so far to be approx. following the sales of the 360s first year at a 50% higher price. Don´t give some the "360 was supply limit", because the sales weren´t exactly sky-rocketing when supply improved.
Now the interesting question when do you think the sales of the 360 will peak?
Interesting peak theory but again this only applies in a bubble. Ps3 and xb360 are going after the same set of gamers. IF xb360 "peaks" next year ($200), it won't matter when ps3 peaks afterward as the userbase will dictate library which will dictate larger userbase etc ... and so on.
For example: When did xb1 "peak"?
Regarding gen longevity: This gen will start to die the second the nextgen systems are announced. By this I mean the sales will start the declining process and the current gen will be completely "dead" (by "dead" I mean no new AAA titles such as this year for ps2 with the last hurah being GOW2) ~ a year after the last nextgen system hits market (IMO 2012)
