The 360 Hd-Dvd add-on is selling for 179.99 at Best Buy and in addition to King Kong (already in the box), you also get the 300 HD-DVD. The 300 Hd-dvd version has been ranked as being better than the Blu-ray version. In addition, there's still 5 free hd-dvd movies you can get by mail-in. So, in sum, it's 180 for the drive plus 7 movies. Since most Hd movies are between 20-30, you're almost getting the drive for free.
Also, the drive works on the PC. Any PC bought within the last 3 years should be powerful enough to process a Hd-dvd movie. End MS viral marketing.
Bioshock is going for $10 cheaper for both PC and Console versions at Circuit City. Regular versions only.
