I highly doubt Barry will be gone all that long. It'll be like when Oliver Queen left Star City after season 3 or when he was "killed" in season 3. Barry will be back in Central City by episode 4. We could see 3 or 4 episodes without him on Team Flash and he's just in the speed force prison doing stuff like Oliver when Tatsu was taking care of him. However, he won't be gone for very long. It's too early for Bart. Maybe season 5, but not season 4. I would like to see him again, though. It does seem like they are setting up Godspeed, but they have said the main villain won't be a speedster. I hope they don't do Godspeed yet.
