I was on ebay, and saw the following ads:
http://www.ebay.com/itm/Bitcoinminer-20-000GH-20TH-MADE-IN-GERMANY-PREORDER-/191756551371?hash=item2ca594c4cb:g:9pgAAOSwAKxWaGs5http://www.ebay.com/itm/Bitcoinminer-10-000GH-10TH-MADE-IN-GERMANY-PREORDER-/191756540547?hash=item2ca5949a83:g:9pgAAOSwAKxWaGs5Clearly the ad creator wrote it originally in German and translated it.
Also, when you look at the yesminers webpage, they now have an image indicating they have these miners in stock.
https://www.yesminers.de/en/mining.htmlEither these people are desperate scammers that won't go away no matter what the circumstances, or it may be worthwhile to wait until January to see if someone gets one of these live units themselves.
Here's my concern: with the current difficulty being as high as it is, with the halving coming up very soon, if these units actually do exist, they will badly damage the existing ROI on an S7's, Avalon 6's, etc. That is scary (or if you have a bunch of these, you'll feel excited).
Something to keep your eyes on folks.
