According to the US iTunes store has added some Tezuka productions. There are the dubbed versions of shows already released in region 1 (Astro 1980s, Black Jack OAVs, Jungle Emperor Leo), as well as the new Phoenix (also dubbed) and a few of the dialogue-free Experimental Short Films.
I don't use the iTunes store, and I'm not sure if I can even look at the US version of it, but if these already up that would mark the first official release of the new Phoenix and its dub, and the first American release of the short films.
