If this is true and INtel begins to sell only mobo/cpu in one unit, I would foresee every mobo manufacturer on the planet filing lawsuits for unfair business practices. Asus, MSI, etc etc are already forced to buy the chipsets from Intel and they arent cheap. To have to pay for CPU's too would pretty much kill those companies.
In a way I could understand it though, because Intel has a very hard time selling what most of the public percieves (and perhaps not incorrectly) as crummy motherboards. I know when I've been looking at the feature sets for this build I'm planning, Intel boards have been the last on my list. They seem to want more money and have fewer features than the leading namebrands (MSI, Asus etc)
Why would anyone want to pay more for an inferior product?
It might not be a bad idea to buy an extra cpu and mobo now because stocks wont last forever, just in case they pull something funky on us.
This could also be good for AMD. They might be the only game in town that offers options. This could be the gimmick they need to get back into the desktop game.
