Heh even with the logo these review quite well. And it should be compatible with the Wii and PS3 as well, though not sure if the Wii even has surround sound.
There's probably others out there that have a built in decoder, Logitech has some good speakers too so maybe check their website out.
Dell has a set of speakers on today:
