The first official release of Summer 2013, Iron Man 3, will arrive three years after its predecessor, though only two years separated Iron Man 2 from the first Iron Man. That pattern is similar to the first three Spider-Man movies. However, Tony Stark will be on screen a year earlier as part of the ensemble of The Avengers, which is scheduled for May 4, 2012, and there's a good chance the character will have cameos in the other Marvel Comics adaptations leading up to that release (Thor, Captain America: The First Avenger) as he did in The Incredible Hulk.
