Personally, I think there haven't been a bunch of new avvies recently for the pure reason that there are over 350 secret ones of them and that's a lot... for over a year they released a new one on every pet day and every special day and I think they got tired of it. Having to come up with places to hide them and then having people on the boards constantly complaining one way or another... "It's too difficult to find the avatar!" "PNG not another stupid clicky..." I found it quite annoying, personally. No one was ever just happy that there were avatars being released in the first place.
