The reference to a show special that will 'knock your eyes out' makes me think of a display monitor or projector. If not one that is Outlaw's own, then some offering through, or bundled with, another brand, similar to Outlaw's offering of the SMS-1.
The words "powerful", "unique", "flexible", and "first of its kind" used in the newsletter make me think of a modular or expandable amp, perhaps at the 300wpc level? These words might also apply to a new processor or receiver, but if I'm not mistaken, that may have been ruled out for now.
As to new offerings that attendees might listen to, perhaps Outlaw is introducing speakers other than the bookshelf - center, surround, mains larger than the bookshelf model, or even a new subwoofer. While I would genuinely be surprised to see Outlaw move toward loudspeakers of an active crossover design, that could also be "powerful", "unique", "flexible", and "first of its kind" for Outlaw.
Just guessing. I know I won't be able to be in New York, so I'll be waiting on show and post-show news like 99+% of Saloon members.
