CES in 2009, and we're just now seeing the first sets ship to consumers in North America. We're just as curious as you as to what caused a nearly 1.5 year delay, but hey, if you've been longing for 5.1 channels of audio in a package that requires nothing more than a source and your dome, we suspect you'll be in the "better late than never" camp. And yeah, the company is indeed charging a borderline insane $299.99 for these, but considering that said outlay buys you an "unfair advantage over the competition through precise 3D sound that drastically heightens awareness of your gaming surroundings," it's fairly easy to justify. Oh, and the public humiliation that'll come with wearing these outside of your basement is on the house. Huzzah!
Update: So, we found out that these have been slipping out in limited quantities since last August to those who pre-ordered, but the flood gates have just now opened up.
