iOS 7 running late; iPad event possibly April?

In a Branch thread stemming from discussion of an iPhone production report, Daring Fireball’s John Gruber wrote that he’s heard that iOS 7 is “running behind,” and engineers have been moved off OS X 10.9 to work on the newest iOS. According to The Wall Street Journal, Apple is expected to ship iOS 7 “around midyear.” An overhaul of the user interface is expected, courtesy of Jonathan Ive’s involvement. Gruber also mentioned that he’d heard nothing regarding a new event, but speculated that Apple could introduce the fifth-generation iPad this month. In the absence of typical pre-announcement signs such as leaks that production is underway, the date for the next iPad’s unveiling has remained ambiguous, with forecasts ranging from April to October of this year.
