I really, really suspect an iWatch release. The 'write the code, change the world' stuff would have far more significance than writing apps for the next OS X/iOS. Plus introducing it at WWDC will give developers an opportunity to optimise their apps.
Finally the timing of Nike discontinuing their fuelband must be important, especially seeing as though Tim Cook is on Nike's board.
It must be, coupled with the ambiguity of the WWDC app, teasing about new stuff coming out. I know it's a lot of speculation, and Apple fans are always overly-cautious about getting hopes up for new stuff ... but it must be.
