I wish they would implement a program on their website where you could pick FFG images and design your own sleeves of differing sizes (ones that are based on FFG products). They could charge a bit more, but I would be ecstatic to pick up deck specific sleeves for Runebound and TI3.
Custom Design System
it would be kinda cool, but it would mean making a press for the image for a total of 50-80-100 sleeves (depending on the game).
That would be cool, by size, by design etc...
