Last report was a yes, current consensus is a no. The author makes the occasional appearance on social media, and expresses the view that she is still working on it, but nothing has yet appeared. This is not uncommon for this mod, but there has been a fair wait now, and Mojang is continuing with it's rapid-fire versions.
Realisically, the mod is incredibly large at this point, and the environment has changed significantly (the things done by both forge and Mojang have caused short-term issues for devs to make life easier in the long run), and the author is unwilling to accept other inputs. Personally, I'll eagerly await developments, but not hold my breath.
If an RP2 update appears, it may not be added to the pack immediately, as it would require a world regen.
