It will be at least SEMA before any real info is available. I think the only big thing you're going to see with the Sport RE is Renesis trigger support and possibly a 3rd injection stage.
The Sprint RE will be essentially the same as the Sprint 500 but will have rotary trigger support.
The new CDI boxes are simply the same tried and true M&W units in a newer case and rebadged as Haltech.
