^That is a more reasonable scenario, yes I agree 60 million is possible, but I would put it around the middle of my expectations, so the X360 will finish with about 60 (55-65) million if trends remain the same.
The possibility of it going higher or lower than 55-65 depends mostly on the PS3, and in some part the Wii..... if the PS3 doesn't "renew" itself within 12-15 months the X360 could reach the heady heights of 70 million (but still not much more) with the PS3 not continuing for very long and lounging around 40-45 million.
If the PS3 gains a bit of momentum this year, and perhaps rolls into next year with weekly sales exceeding the X360 again, and then doesn't stop there, I think the X360 will stop short of 55 million, likely around 50 million, with the PS3 catching it (eventually) and making around 55-60 million.
