Saw this on their website. Very interesting, good thing I already have one of the 1080p HD ones.
GoPro:Soon you'll be able to combine two HD HERO cameras in one housing with a synchronization cable to shoot full 1080p 3D video. All 1080p HD HERO cameras will be compatible with the 3D HERO Expansion kit.
Owning two 1080p HD HERO cameras makes more sense than ever before. Capture multiple angles at once using both as individual cameras or combine them with the 3D HERO Expansion Kit to shoot 1080p 3D video.
GoPro, bringing you the most versatile cameras in the world.™
