From the V-cube newsletter/ email update I just got:
We are in the process of building up our stock for the flat and black versions of the cube in order to cope with the high demand from our fans. The enthusiastic and overwhelming reactions we have received so far though led us to the early release of the V-CUBE™ 4b to give our fans a taste of what we believe to be the best 4x4 cube in the market!
