Consoles are on longer cycles than phones. There is fragmentation to consider which console makers will always avoid. Not to mention the fact that they aren't subsidized nor are they sold on a contract basis, so you don't have tons of customers constantly coming off contract anxious to get the latest and greatest. There was a Nintendo v2, v3... they were known as the Super Nintendo, Nintendo 64 and so on, but they came out several years apart, of course. XB360 is going on 7 years now, etc. But that works for consoles. Something new coming out every 3 months or so works for phones and how they are done with carriers.
