Essentially with the PM , my understanding from P2Max is its with Campy for testing... they had mentioned it all depends if they want to use the "old" crank design, or a new one. SRM has already stated to me that they have no intentions on redesigning the Campagnolo model.. Someone else mentioned on here many pages ago that stages would be developing a PM based on the new crank.. P2Max will redesign if Campy changes the arms (Campy supplies the exact same arms to P2Max and SRM)... Id think there would be 12 speed PM solution soon, I havent seen any clear pics of a PM on any of the 12 spd EPS guinea pig bikes... they all seem to be using the new crank...
I am aware of what you've pointed out... Actually the arms sent to P2M and SRM are both the same. As a matter of fact, the P2M and SRM PMs are almost indentical in the spider design as well. I'd think that if the 12sp chainrings are the deal killer in all these issues, just having the same arms with a new pretty decal, won't cut it. One mistake, I think, Campy made when they created 11 speed, is that they emblazoned "11 SPEED" on most of their components, rather than just "Super Record" or "Recond" as they now have. It would be a pitty if SRM/P2M come up with a new "12 Speed" spider, that could use the old arms. I'd rather send in my old arms and have them install the new spider, rather than spending more money just to have an upadted decal!!!
I think P2M and SRM should see if there is a modification needed to the spider to make it work with a 12sp drive train. By the way, these cranksets used by P2M and SRM are not really "Super Record" or "Record". They are hybrid cranksets made in collaboration with Campy. The arms, as you said, are supplied by Campy, but they have CULT bearings AND a steel spindle, similar to a Record crankset. But the bearings are what a Super Record crankset has. Therefore, I'd see another hybrid crankset made by these companies.
P2M seems to be more involved in this, because of the Movistar sponsorship. But I'd be hard pressed to believe they would go through all the trouble to make a Super Record 12sp specific spider, to be compatible with these SR 12 "reinforced chainrings":

However, the Record 12sp crankset seems to offer pretty much the same "advantages" of the SR, but the chainrings would be much easy to install on a spider designed as the ones seen on the current SRM and P2M:

personally wouldn't waste my time with Stages or other power meters any time soon...
