which events are getting a rerun in the upcoming year

This year, we will have Christmass (Rider Artoria Alter Santa), after this years new halloween.

Next year, GudaGuda 1(Archer Nobunaga) around early march/late february...

Rashomon, Journey to West, Onigashima (Kintoki Rider), this year Summer (Assassin Scat) and this year upcoming Halloween (Saber Liz) and Christmass (Lancer Jalter Lily).

I heard some rumors about a "Fate/Zero Accel Order" Rerun for next year, but I don't think this will happen. Maybe 2020.
