A "few right now"? Did you follow the link?
There are 32 systems shipping next day or within a couple of days. A "few" ?????
It's much more likely that the turtlenecked overlord is throwing a massive hissy-fit about his mistake in stiffing Intel and going with Nvidia chipsets (e.g. 9400M) and now the engineers are struggling to redo every motherboard without changing the holy unibody chassis.

I mean, next Tuesday for sure.
Don't believe the hype - the i series of processors from Intel are all very nice but I doubt you'll see i7 in a MacBook Pro because it would make it larger and heavier. i5 and i3 have some neat features but like the extra cores on the desktop, there is a dire lack by software vendors taking advantage of them so even if you do go out and could purchase one - don't expect a massive boost instantly.
As for the rest, I doubt that'll require massive redesign since it would have been very short sighted designing something specifically for a given motherboard (and in turn chipset) given the world of IT is turbulent.
