I believe that this is a permanent exit from the SAN storage business - for all the reasons in your second paragraph.
Partnering with a company that specializes in storage is a smart move - it's just part of Apple's transition from a computer company to an electronic gadget company.

They aren't exiting this business. They are using XSan to be the Microsoft of Storage Network Hardware Vendors.
