The MPLE was available at blade last year before it was up at the site. I wouldn't be surprised if brought a long a few S5s.
I don't recall clearly, but I don't remember the MPLE being a normal release. As far as online sales went, wasn't the MPLE just a "Dog Bowl" of leftovers from Blade? They still had some MPLEs at the Spring 09 Knob Creek, so they might still have a few for Blade, but I don't really think S5 CGs will be there -- I'd be less surprised if that's where S5 LEs are released (especially if they're INFI and very low volume).
