hi, i'm wondering what people think the likelihood of a macbook pro update coming before new mac pros come out. the reason i'm asking is because i want to my 15" 2.4 Ghz MBP in order to buy a mac pro. the reason i want to switch to a desktop system is because my MBP almost never leaves my desk anyway and the thought of quad (or octo) core workstation with more customization options has me salivating. i'm also going to be attending a school next year that requires you buy a new MBP from them and i certainly don't need 2 laptops. so anyway, i'm waiting for new mac pros to come out before i sell my laptop because i don't want to be without a computer indefinitely but i don't want new MBPs to be released before then, thus devaluing the one i have now. so what do you think i should do?
