Time Confirmed: Arrow of Time for Particles

[Quantumental]

So there's some potentially quite interesting news circulating:

http://blogs.nature.com/news/2012/11/particle-physicists-confirm-arrow-of-time-for-b-mesons.html

and

http://physics.aps.org/articles/v5/129

So if the arrow of time has been confirmed for these particles doesn't this have some consequences on for instance retrocausal models of QM?

I would assume that the TCP theorem still holds, and that reversibility is still possible.
