- It's too expensive.
- How many people would buy the same character twice?
- Ed's height probably needs a new body.
- If demand is high enough, they would have done so already, together with the Shamballa Al.
- And up till now, characters have been released in pairs. Who will be paired up with Ed? The remaining characters are a bit weak in terms of popularity.
On this forum, there's a photo showing all 4 of them lined up (too bad, can't see much of Ed) . Seems to be from a toy show. Mustang is about the same height as the armour Al, while Shamballa Al is the same size as Ed.
