WWDC 2013 WWDC 2012 WWDC 2011 Some say its colorful and looks like icons which could hint at an iOS revamp but WWDC 2012 logo was colorful and was made up of these squares too. Only thing that looks different is 1) No Apple logo 2) XIII instead of 13 But lets be honest, people know is about Apple because it literally says 'Apple Worldwide Developer Conference' at the bottom and I think most people know the year is 2013.

Tbh there previous ones were basically either showing a ton of apps or an apple logo. Plus they need a good laugh at all those people ciphering the hidden code of the WWDC logo.
