I think pushing back the MBPs is all part of a marketing strategy. And it also gives apple time to polish/tweak/perfectionate.
Since apple might be a little unsure about how the iPad will do (when it comes to sales), by pushing the MBPs back, some of those who are waiting on the MBPs will get antsy and buy an iPad (contributing to the sales).
However when the MBPs release, those ppl will still buy one, because the iPad will never be an alternative to a mbp in terms of features/performance , so buying and iPad was a mistake/impulse buy in the first place. Apple win.
So , if this holds true, MBPs wont release for at least a month after the ipad
