After some internet trawling, I'm confused...seems the Code gets some minor upgrades for 2012, does anybody know what the real story is here? Can't really tell if these are changes that make a significant difference. New rotor apparently, and a new bladder....don't know how crucial either of these are. Reason for asking is I'm about to pull the trigger on a pair, wondering if it's worth waiting for the 2012, or if 2011 is good to go. Along those lines, has anybody seen 2012 Codes ship at this point? Some shops are claiming stock availability...

Note: talking about the regular Code, not the "R"...

thanks!
