I think C3d SP1 last year was release very close to SP1 for the base. If the rumour is true that it gets release tommorrow - there has been plenty of time since Shaan Hurley indicated that the beta Update 1 was in testing and tommorrow. I will venture my guess, that yes it should be included.
As for stepping up - absolutely. I like the bleeding edge.
