Am I somehow to understand IDW actually ran so dry of material we have a comic after the fashion of the Hearthswarming Pageant episode but retelling the wizard of oz but in Equestria, which is Odd ?

I guess so.
Also there may be a new build of FiM-the-game in the works. Get your C&Ds ready colts, we're summoning Scootermina, who looks like Pinkamena but with a palette swap
