As far as Chucky's resurrection goes, I really hope that:
1. He will be resurrected differently from how it was done in Bride of Chucky.
2. At the beginning of the movie his per-resurrected form is how it was left in Child's play 3. Not in a completely different form like how the Leprechaun was in a frozen form at the beginning of Leprechaun 3 when he died in a completely different way at the end of Leprechaun 2.
3. There will be a resurrection scene. Not like the beginning of Jason Goes to Hell or Freddy's Dead when they just appear without an explanation of how they came back to life.
