If we are talking about Worldwide sales the PS3 will easily outsell the 360 by far more than just 50k units/week. I think 100-150k is more realistic on a global scale.
The Ps3 also has a 10 year life span, so 3 years is really just half of its life cycle if you think about it, but it will likely have passed the 360 in 2 years at most.
