Apple's marketing strategy can partially be explained by the Osborn Effect as explained on Wikipedia. http://en.wikipedia.org/wiki/Osborne_effect
"Most technology companies today guard against the Osborne effect by very strictly controlling information. In general, the stronger the market position of a company, the less it will reveal about product plans and pricing. Apple, Inc., for instance, have been traditionally, and remain, very tight-lipped about new hardware releases (resulting in a substantial Apple "rumour industry.")"
