So have you done any benchmarking on this? I have something similar:

Supermicro running DSS 5.0
Dual Qlogic 2460 (working active/active FC MPIO would be great - )
Promise Vtrak E610fD w/ 16 147GB 15k SAS drives.

Just wondering if using DAS SAS gives better performance that the direct attached 4GB FC.

theoretically yes it should be better. I think that its faster because its talking native disk language end to end. im not positive however but i will be testing that fairly soon:

dual port 4gb fiber channel VS. dual port 3gb SAS

I think SAS is more expandable by design as well. Just wait till you see SAS SAN's - people will be running back to fiber channel because it seems a heck of a lot more complex now.
