Does Apple's website change signal the switch from aluminum to liquid metal?

Are Apple’s computers heading to a darker liquid metal from their now standard aluminum just like the bar on the Apple.com website (and Lion OS)?  Perhaps, we’re not sure if the new material makes a good exterior shell.  But Apple has invested into the new technology that is radio transparant and has some unique properties (like crazy bounce!).  Some have noted that the change in color change of the top bar coincides with the new material’s outward appearance:

Reports have suggested that Apple would use the liquid metal in battery cases and it was revealed by Cult of Mac that Apple was already using the material as the SIM ejector tool in iPhones.
