If new iMacs are released in October of this year, with upgraded internals, how much does that affect older models? The current model I am looking at is $1999 so I am just curious, in the experience of those who have been through this, how much off do you think retailers like B&H Photo will offer last year's model for? For someone like me, it would make sense getting sticking with last year's model (unless something crazy is introduced) and saving the money. I am hoping if the prices lower significantly, I can upgrade the one I want from a 2TB Fusion Drive to a 512GB SSD at the 1999 price. *Not sure how to edit title, but it should indicate Affect not "effect". thanks.
