Personally I'm relieved that this is a scam. I mean, seriously, one mini rig replaces about 20%-25% of all mining globally? Sounds like a bad thing for the average miner who doesn't have thousands of dollars to throw around...or in my case even $500 would be breaking the bank. So, yeah, for self-serving reasons I hope it remains GPU based...at least this way I have a nice card for gaming as well as mining.
