I saw this, and to be honest can't think why they'd bother making it wireless if then then stick that great big fugly black battery/control box on there. if it was hidden in the frame somwhere and you could get rid of all external cables then that would be much better.
If it is compatible with shimano and campagnolo 10 and 11s cassettes, then I can see that being a useful feature though. I don't think it looks too bad either, with the exception of the control box and the rear mech wire.
Full wireless would be better, but might cause problems with battery life and charging.
I guess it's only the prototype, even so it's not a pretty-looking item by Tiso standards. The Sereo/Altero cable-shift rear derailleur is a far more pleasing item.
