*Last* Tuesday, as in February 26th, the Apple Store online gave an estimated ship date of 2-4 business days for the upper 15.4" MBP. The next day, it said 1-2 business days. Sweet.
It has said 1-2 business days ever since. I know; I've been checking it daily. Both the lower 15.4" and the 17" MBPs are shipping within 24 hours.
Meanwhile, Amazon, where I ordered the upper 15.4" MBP (for the rebate and free Prime shipping) has said April 30th all this time. I assume that's just because they don't really know when they will come in; my friend ordered a TomTom GPS from Amazon that shipped within two days rather than the stated estimate of 3 weeks.
I don't understand what's so different between the two 15.4" MBPs that one is currently shipping and the other isn't. Do they not have enough 2.5 GHz chips, or is 512 MB of graphics memory hard to come by, or what?

Edited to add: My friend ordered a non-Pro MacBook on Amazon the day they were released, and it shipped the next day.
