Yeah, the move is pretty clearly a ratings thing. If the show did better in the ratings, there would be no concerns with the budget. Budgets are based on ratings, which is why popular shows get big budgets, and low rated shows get their budgets cut. If CBS was happy with the ratings there is no way they would have given it up, and there would have been no question about whether it was going to be renewed before the news came out. It's also worth keeping in mind that CW shows don't need to get the same size ratings as shows on CBS, so there is a much bigger threshold for success. So a show with OK ratings on CBS could end up being considered a big hit on The CW. I don't see the network making a difference about the CW characters they can use. It's still being produced by all of the same people and companies. Rights like that are entirely based around production company, not the network. if the network mattered then I doubt Supergirl or Gotham would be using DC characters since neither of those networks are owned by WB. Yeah, I don't see them merging it with the Arrowverse. I definitely see more crossovers, but I see it remaining on a separate Earth. They've spent so much time setting up a different universe and I really can't see them dumping that just because it's moving to the CW. I honestly didn't think of that, but I could see them bring in some doppelgangers.
