We were half-expecting the next generation BMW Z4 to be revealed at last week's LA Auto Show, but instead, we got an eye-full of the new twin-turbocharged V8 7-series and its ActiveHybrid variant. Yesterday, came word that the new coupe and roadster would be unveiled sometime next month and now, we've got a date: December 15th. BMW has launched a teaser site at http://www.bmw.com/joy that seems to imply that the Z4 will come in a variety of vibrant colors. Either that, or BMW is trying its hand at producing a combination slasher film/laundry detergent commercial.
There's no actual mention of the Z4, or any other car, on the site, just this odd little video that you can check out after the jump. Expect more details to be revealed in the coming weeks and look forward to live photos of the 2010 Z4 from the Detroit Auto Show in January.
