well the good thing is prices never really drop on apple products...(
Not necessarily... Every time Apple releases a radically new design, they have to recoup the cost of R&D, so the first iterations of that design usually cost a lot more than products of the same design later on. Take the MacBook Air for example. It was a completely new direction in laptop design. And the introductory price was pretty hefty for what you get. $1799 for the same performance level as the entry level $999 MacBook. Fast forward 4-5 years, the MBA's compares well with other laptops in price/performance.
I can see a 12 core MP costing only $4K in 2-3 years. No more R&D cost needed to be tacked on.
