Considering A15 was announced a little over 2 years ago (2010 iirc), and it's JUST now getting into production devices with the Nexus 10 (not counting Krait which is similarish to A15), when they say due in 2014, I'd bet you won't really see them in use until early 2015...Still though it'd be great to know that the P2 supported it when it came out, so a whole new system doesn't have to be developed around it. Modularity is nice.
