I don't see them releasing all of the reissues along with a new EP on the same day if for no other reason that they wouldn't want to diminish the sales of either category. A lot of people might skip over one thing and buy another and it would hit the EP's performance. Especially since they've been working with major labels again, I'd be surprised if they'd be allowed to do that (or would even want to). If it isn't that March date from the slipmat then I think it'll probably be closer to touring. I'd love to be very wrong though!
