Nintendo's Wii isn't even out yet and already there's an upgrade in the works.

When the first version of the Wii comes out this Sunday, it will be lacking one thing its competitors have: the ability to play DVDs. Now Sonic Solutions, makers of CD/DVD burning software, and a Nintendo rep have confirmed that DVD viewing is expected in the back half of 2007. So if you're going to want to watch movies on your Wii, you may want to hold off, um, a year.
