2011 vs 2012 version of PCV - Any differences (other than price?)

Im going to post this more specific question in the tuner section, but researching the pricing they seem to have several of "last years" model available for under $320 USD and they are listed for roadsters from 2008 -2011. The "new model" for 2012 is still around $355 and shows for 2011-2012 Roadsters. Any of you tech Genius's know if anything was actually changed or if I can save around $40 (which would cover the 02 sensor mod) buying the model listed for 2011?

Im new to the forum, and wanting all the info I can get before jumping in and spending too much time or money.
