D-Wave has a history of making tall claims. Scott Aaronson (MIT EECS prof who works on quantum computing/complexity theory) has written about them a few times. http://www.scottaaronson.com/blog/?p=306 He mentions, however, that "The people at D-Wave are not conscious frauds; they genuinely believe in what they’re doing."
Thanks, the article was scant on details as to what, exactly, they hope to prove by this. Given the blog post that you linked to, it sounds like they are still not going to gain credibility among the science community that their system is exhibiting quantum effects, and the times article makes it sound like a publicity stunt.
