No category is ever without an editor. It may not have a listed editor, but any catmod, editall or Meta editor can edit there. There is also no way that we can say how long it will take. Someone may breeze in tomorrow and review everything in the category, or it may be some weeks or months. Someone may decide to start by deleting all the spam there, or by listing sites that look listable. I don't know, and neither does anyone else. The best anyone can do, is give you the current status: listed, waiting, likely to be rejected, or rejected.
