Any plans to release a smaller Thunderbolt interface?

Just curious if there were any plans to produce a smaller (fewer chaels) version of the Thunderbolt interface...

I currently use an AudioBox for my home studio setup, to drive my studio monitors and do any one or two track recording touch ups.

(For mobile/field recording, I use FireStudio project)

A 2-4 chael version that could sit on a desktop would be great!

thanks!
