When Vaultbreaker was announced it was assumed it's based on the same chips as Flower Tech, for a couple of reasons: CEO had mentioned Flower as one of companies he was talking to, and specs seemed to match. Flower recently announced that they failed to produce their miner and postponed delivery until February. GAW insists they will still deliver on time, i.e. end of Q3 / beginning of Q4.
If GAW releases a VB before February, it will be a new color of hashlets. I don't expect to see a physical VB before end Q1 2015, at which time they will be pretty useless.
