Personally I'd love just plain old macros for it. Tactical switches as well, rapid fire / dropshot, turbo knifes, etc. No need for extreme macros, even basic ones are good, but there needs to be a community. You shouldn't have to be the only one creating the macros. Like with the xbox 360 macro controller, everyone should be able to create macros. Even an in between legacy-macro controller will be awesome.
