Personally, I like how there hasn't been any 12" announcements lately. It's good to WANT an announcement. There has to be some hunger to keep my collecting fire alive.
Everyone wants everything now. Give me all my favorite main characters this instant! I'm not of that mindset. I want them all.. over years! Give me some cool aliens, creatures and minor characters to mix in and keep it fun! Take your time and keep quality as high as possible!
That said... I feel for the LOTR PF folks. It has been TOO long for that line between pieces. There is a point where a line can become ice cold for collectors because the wait seems endless.
This is what is perfect for me (I stress for ME) from the Star Wars line:
8 - 12" per year (1 or 2 being convention exclusives)
3 - PF per year (super high quality!)
2 - misc items (creature packs, accessories etc)
3 - dioramas per year (1 being an exclusive)
Just my thoughts.
