Well, that's different. The next major iteration of Android will be called Kit Kat, it seems. We know this because Android boss Sundar Pichai just tweeted a photo of a gigantic Android robot made of Kit Kats.
Apparently that's going to come along with a promo campaign in Kit Kats to win a free Nexus 7 or Google Play credit, which is a strange and probably unnecessary bit of advertising, but fine. Your operating system is a supermarket aisle ad now is all.
For the uninitiated, major releases of Android get dessert names, and they've been progressing in alphabetical order. So Ice Cream Sandwich was succeeded by Jelly Bean, and now Kit Kat. Our dumb but prescient guess in 2010 was Krispy Kreme.
