As far as I know, the new group (Pixie Dust) is using the translations from the Rippersanime group. The future of the scanlations depends on whether or not those translations continue, unless the group at some point gets its own TLer of course.
Personally I hope it continues. I've got a shelf full of Alita, and so have two of my relatives. That wouldn't have happened without the scanlations. But it's not my decision after all.
Probably because group doesn't have "forum, website, or IRC channel", but they already released two chapters (via Tokyo Toshokan and Mangatraders). I guess it's not my place to judge the rules, but at least a bit of feedback would be good. Lack of any notification why those submissions were rejected discourages me as an updater.
