I do not have any information- he hasn't provided it but at the same time, I haven't asked as I just am not interested. I have always felt that production numbers are sales gimmicks and that the toy soldiers either stand on their own or they don't. So far as I know, Jenkins and KC release that information but other companies do as well- Conte does on occasion- like the Roman war galley and some of the Russian manufacturers do with really limited pieces (ie sets of 10).
I have yet to be convinced that releasing production numbers does anything to enhance a products appeal. Some of the larger russian distributors say that certain figures are "limited editions of 10 figures" and they sit and sit with that hefty $3,000 pricetag. Even Conte's roman war galleys can still be had, per their website, at the discount price of $400 and they are limited edits of 200.
If I had to take an educated guess with EoI though, based on what I have seen with the Colonials and the Samurai's I would say the runs are in the 3-500 range, though, I believe the Samurai's are quite popular in Japan so the runs may be higher. I believe the Roman collection will offer a new variable for Ken to manage in the fact that this is a departure from offering 3 man sets. A lot of these figures will be individual figures. I have to think that provides the collector more versatility in posing these figures and the demand for certain figures could be wild across the boards.
Take the Centurion for example- how many Centurions should really be shown in a diorama?? Then how many of the fighting legionaires should be shown?? I am planning on buying tons of the legionaires and cavalry figures but really won't need too many of the Centurions (St. Pete will really provide them for me in truth). Looking at it from that perspective, the demand for the Centurions could be pretty healthy initially and then drop way off so the production run might not be as high. The legionaires though, could enjoy significant sales volume for a very very long time.
Of course, that's assuming that Ken hurries up and returns from Hispania soon and gets these legionaires out to us
