This is a very unimpressive article. I am surprised to see Colin link to it.
In particular, while the paper the article references in a short part between the history lesson is important, it does not actually change things much.
It rules out those who think that the wave function is a distribution over an underlying reality but it does not affect those who believe that there is no hidden reality. So called Quantum Bayesians (imo the clearest not necessarily best framework). Nor does it affect the Many Worlders who think the wave function is real, and no hidden variables. Non Local Hidden Variable Theories with real wave functions are still acceptable. So things are no where near as clear cut settled as the article would have you think.
And even for those who believe the wave function is an epistemic tool for an underlying reality, they can still abandon Bell's framework using exotic escape routes like "retro causality". See Matt Leifler's blog for more on that: http://mattleifer.info/2011/11/20/can-the-quantum-state-be-i...
