Not necessarily after January.
It might aswell be released during January, if beta testing goes well. It allt really depends on how the beta testing goes I guess, now.
If the beta team finds the mod is alright, it gets released.
If they find something that needs fixing, it could be delayed (consider that usually once a fix gets deployed it gets pushed to the testers, then it gets tested to see if it solves the original problem and for possible unwanted side effects, and so on).
