did some more research.

all the i5/i7 macbooks seem to be running on the Arrandale line, so that would make them all dual core.

it looks like the top i7 macbook is using the Intel Core i7-620M processor. the two i5 models are the Intel Core i5-520M (2.4GHz) and the Intel Core i5-540M (2.53GHz).

Any chance the 15" i7 has quad core? I know battery life is precious but I wish they would put one hardcore laptop out and price it high if needed.

I found the answer. Sorry. Dual core on the 15" i7. http://ark.intel.com/Product.aspx?id=43560
