If they aren't putting it out for independent testing then it sounds to me like it sucks. If you have a great product you want everyone to know. If you have a crappy product you want no one to know until you have sold as many as possible.
Or Maybe AMD's Learned from their Mistakes with the Nano, and isn't going to send review samples to specific reviewers.
Still, I'd rather wait until we have benchmark results showing up from reviewers before making any conclusions on the Pro Duo.
Also, I agree that $1,500 is too much of an asking price for AMD. The Titan X from Nvidia is $1,000, and if It can't even beat a 980ti, AMD will only be digging further down. I expect price drops over the next couple of months, similar to what happened with the 295X2.
Until then, I suggest waiting out for now.
