There eventually was a Edited Manga of 322, but the translation was kinda off because everyone who did a translation was working off the flawed Spanish translation. I may go back and do a better translation of it if I can find some decent raws. Right now I'm working on translating this chapter...
I was unaware that they had cracked the alien alphabet. I made my own English translation of chapter 322 using parts of the raw and the Spanish Edited Manga (I'm pretty sure the only Spanish Edited Manga out there is Gotei Konoha's), hosted it on my website at http://www.soulraver.net/gantz322.html...
