ok i think that there will be alot more romance, mostly between Ron and Hermoine. Snape is going to side with Harry but still act the same during classes. Malfoy is going to side with Harry for some odd reason, and there will be some long dramatic kiss between harry and ginny. (Does Ginny still even like Harry any more??) And something is going to happen with Hagrid, death, leaving of some kind i don't know but somethings is definantly going to happen
As a fan of the Harry and Ginny pairing, I am in hopes that they will share a few significant moments in Book VI. Also, I am in fear Hagrid might die or something, I am not sure where that story arc is heading. And I guess it remains to be seen how the Ministry will act, now they know Voldermort is back.
