I can't imagine the show being canceled, that just wouldn't fit with everything so far.
The show being moved to another timeslot is a possibility, apparently it's not the first time such a thing happens.
But what I think is that they might take a few months hiatus. They've been going on through the arcs non-stop, and it seems they didn't even actually had time to correct EVERY SINGLE THING and make a totally new opening from A to Z for the Cell arc.
So I think they might put the show on hiatus, to breathe a little maybe, but also to have additionnal time, to have a head start with the final arc and possibly recreate a brand new opening, rework more scenes with more special effects and maybe create the few minutes for the new Kanzenban ending.
I'm probably much too optimistic about the better re-worked parts (I'm already completely satisfied by the rest of the show for now, I'm not saying they SHOULD do better), but I think a few months hiatus would make sense for them to release the pressure and then upgrade the global rendering of the show for its big finale by having a big head start on production before it actually starts airing, with more than one week to work on certain episodes if necessary.
I would prefer that they keep going in a new timeslot though, cause their job is really fine until now, it's more than enough for me and I'm not strong on being patient, I like to have my new episode every single week!
So my opinion is:
- CANCELATION: highly unlikely, nearly impossible, it won't happen.
- NEW TIMESLOT: absolutely possible.
- HIATUS: very likely.
