The 330M and 320M have been around for quite some time. If I get a new laptop some time this summer, it has to have at least 330M and it has to be below 15 inch. Apple tends to update their graphics cards every 1-2 updates. Considering this has been a very long update, there probably will be new graphics cards. They could fit a 320M in the 11.6" Air, they can do better with the 13" MBP.
