Tom Gilliland, Sideshow's Art Director (if I remember correctly) recently had a chat (link is in the new newsletter) where he stated that the Star Wars 12" line would be slowing down some now. He made it sound like they had a lot of figures ready in advance but that they are caught up to them now. And that they will tend to release them in blocks.
A chatter asked if there would be Stormtroopers this year and all he said was that Imperial Troops (not specific) were not TOO far off in the future.
I prefer one every week, but at least I'll be able to recover from the stress of the priority pre-orders.
I hope they fill in the time with LOTR 1/6 scale stuff.
