A delay for the Sandy Bridge Macs is on the cards?

Intel announced yesterday to have discovered a design defect in its Cougar Point controllers, those intended for the machines equipped with Sandy Bridge processors. This defect relates to four of the six SATA 3 ports of these controllers whose performances can be degraded and that are not even recognized by the machine anymore.
The only means of fixing this defect is to produce a new revision of these chips what will happen at the end of February. While waiting, Intel ceased marketing these controllers and has recalled all the mother boards already sold that could cost the foundry 1 billion dollar.

It should thus be increasingly difficult to get Sandy Bridge computers, at least those that have more than two SATA ports SATA. In practice, this should have an impact on the release of certain iMac, the 27" models current having 3 SATA ports cables, but also probably for next Mac Pro that use the 6 available ports.
For the portables, it would be possible in theory to use these defective controllers since until now Apple has used only two SATA controllers, for the hard drive and for Superdrive.
Since the situation will probably be difficult until April, there are strong chances that Apple is obliged to shift by a few weeks the release of its new machines.
