I'm sure it will work. Apple will do with the macbook pros what they did to the iMacs most likely. When apple first introduced the iMacs with lynnfield cpus, they only had them run with 1066mhz ram, but with the refresh in mid 2010, Apple put 1333mhz ram in the same lynnfield iMacs (and of course the other clarkdale iMacs that came out)
