Title: Re: Pokémon Adventures Volumes 9 and 10 as well as Pokémon D...
I agree that it seems slow, and if they keep up this speed (one book every two months), it won't be until summer 2013 that they catch up to where Chuang Yi is now (never mind where they'll be in 2013). But when you think about it, they're doing brand new translations for Volumes 8 and up, right? (They wouldn't dare release the shoddy translations of Chuang Yi, would they?) There's probably more work to do on these than you think.
Plus, they've got to give the kids enough time to save up the $10 they need for the next volume. ;)
