Ooh, this one is easy... When I try the new Campagnolo product, if I like it more, I might eventually get it. If I don't find it appreciably better, then I still want to get Di2. One thing that has continued to keep Campag products off my bikes, is the stupid proprietary freehub design. Shimano/Sram wheelsets are just so much more readily available, and I like having options.
