A comic from 05.01.2012. Things really happened back from then:  
*New Applejack episodes and more focus on her.  
*Gilda’s return.  
*Seaponies (if we count Sirens).  
*Derpy talks again (next episode).  
*There is humans in Equestria Girl movies.  
*Flim Flam returned (previous season).  
*Twilight is the new alicorn, someone’s OC is appeared in the show.  
*Luna gets much more attention than her sister.  
Trixie is already returned.
 
Only thing we need is Gummy.
