i hope ron and hermione finally start uo something and harry getting over cho and get with lavender or patil (not ginny) and also he stop yelling and continue with the DA
and i'd really like ravenclaw and hufflepuff to have a bigger participation.
oh, and maybe lupin falling in love with tonks...
i think also harry's going to have a hard time with draco and other slytherins at hogwarts
