So since the new MBA will most likely have Sandy Bridge, better flash memory storage, thunderbolt, as well as the portability factor, won't it become a fierce competitor with the MBA 13 inch line. It seems like the only major thing the MBP 13s have over the MBAs is 4gigs of ram while the new MBA will most likely still have 2gigs. I was going to buy a MBP 13 over the current MBA because of the performance difference, but now I think its better to wait for the new MBAs to come out before deciding.
