Oh, Phinnaeus Gage, so you started this thread!

This week, they published some so-called "pictures," but they're all computer graphics:

... still seem to be a scam.

They also said they're going to the conference [http://texasbitcoinconference.com/] in Texas. If the directors show up, I'd be quite convinced (still not 100%) they are NOT a scam. The conference starts March 5th.
