Apple has already adopted it, and Motorola is now all in, so why not Google? It appears Google is going to adopt the nano SIM size for the Nexus 5. A Ukrainian carrier called life :) states on their disclaimer page, “Planning to buy iPhone 5S, iPhone 5c, Nexus 5 or smartphone with Android 4.4? Choose nano-sim from life :)” Now I have no idea why they would say “or smartphone with Android 4.4” because that implies that Android 4.4 would require a device with a nano-SIM slot. I don’t have to tell you how ridiculous that would be.
