They cite many decent sources that seem to corroborate this, though none as respectable as Nature.
What's interesting about the Nature news article is that it very carefully avoids making any definite claims of what is going to happen if things stay the same. The author points out that pollinators are important to the ecosystem (true, of course) and that they're "under threat", which seems intended to imply that the stability of the ecosystem itself is under threat. But no explicit claims about the impact of on the ecosystem at large are actually made in the article.
As a layman, I'm not sure what to make of this. At this stage, it seems like these studies are mostly of interest to researchers, and there is no real need for the general public to worry about "A World Without Bees", yet that's probably going to be the popular interpretation anyway.
