Except they did in 5 years what another did in 10 (2006-2016).
PS2 was roughly at the same mark after 5-years, and it ended its 10year production cycle in US @ 53.65M - nearly 2x of PS3.
Actually that makes for an interesting point - unless I'm missing something 360 5 years in was just about half of its LTD in US. Granted it did the rest at much lower price, so revenues were down, but unit-bump looks bigger to me than anything we can reasonably expect from 1x or Pro in the same 5 year span. Hell it might have even outsold PS2 if we just compare last 5 years of each console.
ZhugeEX,
MatPiscatella - can either of you comment on that?
