A lot of people who play Armada (and by "a lot" I mean far more than I would have guessed) seem to be happy with a slow release schedule for new content. They cite that their wallets are grateful for having less to buy. Some have also stated that FFG likely can only produce so much product in a given year, and with multiple miniatures games out now, they might not have the production means to make more than 2 expansions per year for Armada.
I feel differently however, considering that the game is so new, and has such a limited selection, it would be better if Armada's production were scaled up to meet or exceed X-Wing's rate of new product, (one or two 4-ship waves per year, plus aces packs in between). And then, if production is an issue, perhaps scale back on other games that already have a ton of product, like X-Wing or perhaps even Imperial Assault.
How do you guys feel? If you only got one wave per year for X-Wing, and lets say, for the sake of argument, it was a smaller-than-normal wave.... (Say, 1 Rebel, 1 Imperial, and 1 Scum). Would you be ok with that if it meant they could catch other games up?
