It's been clear that the D-Wave machine is exhibiting quantum effects for several years now. See Aaronson's blog (http://www.scottaaronson.com/blog/?p=1400 http://www.scottaaronson.com/blog/?p=1400) and this Nature Communications paper (http://www.nature.com/ncomms/journal/v4/n5/abs/ncomms2920.html http://www.nature.com/ncomms/journal/v4/n5/abs/ncomms2920.ht...). On the other hand, it's still not clear that this results in computationally relevant speedups. In my mind, this is not much of a shift in the status quo.
