Which CPUs are there in Surface Pro 3? I was sure the Broadwell Microsoft won't release them for another half a year, because Broadwell CPUs are not announced yet and are expected early next year, or for Christmas season at best. I wonder whether they are the same Haswell CPUs as in SP2, or did MS get a very special treatment from Intel for Broadwell CPUs?
