Right, articles like this are often short on crucial details, it's speculation until we see the research papers.

Re causality etc., as I mentioned above, if the duration of wavefunction collapse can actually be measured then this puts a whole new spin on the matter (sorry, puns aren't my forte but it seemed appropriate here). ;-)
