Others have mentioned a rumour of someone paying $14m for the above and the promise to delay everyone else's shipments to pre-mine being the reason for the Bitsyncom split, but I'm not sure where that's from, but it's mentioned somewhere in that WTF Avalon thread. In any case those chips were proven as you can see to exist a month ago and posted by a disenchanted former member of Bitsyncom's design team, Gridchip.
Furthermore Terrahsh and Burnin' already have 'customers' demanding full refunds as they don't believe they will see ROI, which is not their fault, and what's worse they've already designed, and manufactured working products and stocked inventory for chips that appear to have been witheld to a point in which they will no longer be of any value if they are not delivered ASAP.
Or was that another source?
(I understand so far that Gridchip took photos of the chips in their trays and mentioned a split, but I want to make sure the story is coming from one and the same person and not two or more people.)
