tomuhs is right, same as all things when mass production starts there is a slow and steady decline of prices until there is a bottom.
It is great to be a consumer as the supply is starting to grow and outpace demand. This does not apply to all aro's though as tomuhs also said as the high end ones will still command high dollar values because they are rarer.
For the everyday person it is great as the cost to get an aro will go down, and eventually we will see this with the consumer pricing going down not just more profits for the importers. There will be a time where the importers can make more money, but there will be a breaking point with those as well.
I saw this post
