I seem to be having a hard time finding in-stock expansions, such as Smoke & Mirrors or Legendary Bahadurs. Will more be sent over to North America soon?
MOE Games looks to have them: http://moe-games.com/aristeia/ Bear in mind that US (and elsewhere) distribution is handled by independent companies like MOE, Alliance, and Golden, rather than CB themselves.
From what I've gathered over the years distributors don't like being stuck with inventory so it makes them a little cagey about ordering stuff :/
FOLLOWUP: Privateer Press (the esteemed competition) posted a bit about the growing pains they've had since moving into a new location. The moral of the story (aka, TL;DR) is if you see something you want announced? Pre-order. Success of the genre is great for us, but it has its own problems. For instance, the moment a new Aristeia expansion is announced I'm already contacting my shop. Its the only reason I'm considering the Infinity: Defiance kickstarter versus supporting my local store when its released.
