I sure hope they update the Mac Pro along with the rest...not that I'm in the market quite yet, as this 4-year old behemoth is still working just fine. My MBP is now 5 years old, and apparently won't be able to make the leap to Mountain Lion. It's a tad slow these days too - with a max. of only 3GB of RAM accessible. So, I'm watching the news re: the next generation of laptops with interest. As I noted in another thread, as long as they have enough storage onboard, I'll be quite happy if they're more like the Airs.
