Not that I know of, but my most recent information comes from this over-a-year-old post: http://www.scottaaronson.com/blog/?p=954 Google buying one doesn't make me shift much one way or another -- D-Wave has built something interesting that seems to be faster than other hardware, they are able to improve from the marketing buzz around 'quantum', but may or may not be using any quantum effects. People like http://jeffjonas.typepad.com/ have algorithms for problems that do increasingly better than the competition with increasingly "harder" or larger instances, so that behavior isn't really that weird.
