Magic Color Changing Logo

I never spend ANY time on the official wow forums or official wow websight but I was on there yesterday checking out WOTLK stuff and reading up on details for character transfer. Any way I stumbled across something that apparently is old hat but I thought it was cool so excuse me for bringing up something stale....

Did any one else notice or read that the logo on the official wow websight in the upperleft of the page is slowly turning from green(burning crusade) to blue(wrath of the lich king).

I thought it was a cool nerdy thing to do. Makes every one get all speculative regarding its signifigants. It probably means nothing but I can just imagine the development team cranking away at WOTLK and every time they complete one of thier "quests" (jobs to do to get WOTLK done) they get a little more blue filled into thier experience bar

Yeah its been like that for a while but it is a nice touch.
