Will Apple's SDK come out before June?

At the Goldman Sachs symposium, Apple dropped more hints about the new iPhone SDK. As expected, Apple will control the distribution of commercial apps via the iTune store. Like I was musing in a previous post, this could be a good thing if it brings up the quality of apps. iLounge reported that they received an invitation to the March 6th event with the words "Entreprise", "SDK" and "Software update". Most likely the biggest problem will be the release schedule, a number of blogs are speculating that the full SDK will not be released until June. Given the nature of Apple, it certainly wouldn't suprise me. This means Apple's is pre-announcing the developer platform to divert attention from jailbreaking iPhones, much like Google did with open-social. It also means developers should be still be focused on webapps for the near future.
