What do you think will happen after Android Z?

Officially announced today by Google, Android M is the 13th major iteration of Android. Can you believe that? It's only been 8 years since the first public version of Android was released (in late 2007), and its 13th major release is already here. Well, almost here, since only a Developer Preview is currently available.
As you may know, starting with Android 1.5 Cupcake, Google gave its OS sweet names, in alphabetical order. After Cupcake we had Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jelly Bean, Kit Kat, Lollipop, and now we have Android M (which will get a proper name later this year).
