Might just be wishful thinking.. but doesn't Apple like to advertise their Macbook Pros as a "family" of high performance machines? It wouldn't make any sense to break up that family by only updating half the lineup. My hope is that Apple is restructuring their lineup. Rather than have 2 13", 3 15" and one 17", they are just having one of each. Those 3 are the base models listed as dummy SKUs, and online you can have BTO with different graphics card and processor speed options. I mean how many of you wanted that 512MB 9600GT but didn't need the 2.8GHz processor, and would have rather had it in the lower 2.4GHz model so that you didn't need to pay extra for power you didn't need?
Anyways, thats my blind optimism at work again.
