Has anybody heard any rumors about the release of a 2nd generation 15" rMBP? A techi at Apple told me that Apple shot their wad with the early release of a 4th gen iPad and that they have no major product for March 2013. Therefor he believes that a 2nd gen rMBP will be the big March release. I, of course will never buy the 1st gen of anything, so I am anxiously waiting
