I'm sitting across from Moscone Center West where, in around 28 hours, Apple executives including CEO Tim Cook will take to the Keynote stage to kickoff their annual developers conference, WWDC 2013. No period in Apple's recent history has been more competitive for them, with rivals Google and Samsung pushing the mobile pace into damn-nearly a sprint, and no period in Apple's recent history has it been so long between keynotes before, almost 8 months having past since the iPad mini even back in October of 2012. Those twin tensions put a lot of expectational pressure on Apple. Everyone is waiting. Everyone is watching. Everyone wants to know -- what will Apple do, and what can Apple do?
