From the original speaker announcement, it looks like Outlaw is planning on introducing the following speaker models besides the bookshelf speaker:

1) A center channel speaker
2) Some sort of surround speakers
3) A floorstanding model

I would then expect to see speaker package deals incorporating some sort of surround sound set-up with subwoofer and maybe even processors and amps. I'm also under the impression that you'll see all of these speaker lines by the end of this year.

I'm also expecting Outlaw to stay with direct radiating speakers as opposed to dipoles such as ML or Magnepan. I just don't see them experimenting with a different technology as much as trying get the most performance out of a well-known method.

Of course, all of the above is just pure speculation but it is based on Outlaw's own announcement and their usual business practice.
