Viz Media has announced new manga releases for the remainder of 2010. The first two are releases of Pokémon Adventures volume 9 and volume 10. The two are set for an October and December release, respectively. Volume 10 of Pokémon Adventures introduces Satoshi Yamamoto's art style to US audiences for the first time; the first nine volumes had Mato as the artist.
Pokemon is just going places jeez...With free time this summer I should probably go through and watch as many episodes as possible as well as read as much manga as possible.
Personally, I think the manga is better than the anime is at this point. I'm probably biased in that I think that the new anime series is one of the more boring aspects of Pokemon, but the manga is phenomenal. You should definitely try and read it at some point.
