Batman is a cash cow so no way in the world they'll cancel ever Batman and Robin. I'll have to follow up on the series but people seem to dislike this recent character Carrie, and it appears that DC is making her the new Robin (unless it's some way of us thinking that and that they got other plans in mind) but it doesn't seem wise to just throw her as a robin when they already lose Damian. They may not want a Robin so they don't want to lose somebody someday. I like the idea that Batman can team up with other heroes like the brave and bold; It'll not show us the interaction of batman and Co. but that character may do things more with Batman and take things at a different perspective.
If Namor can beat Wolverine a couple of times I'm pretty sure Aquaman can do the same. If Aquaman can just some how knock Wolverine flying into the river, Wolverine will just sank to the bottom due to his heavy adamantium.
I only liked that origin story of Catwoman in the Batman Returns film because it was just in the movie continuing in itself. Even in Batman TAS had a better origin story for her. The only reason they used that origin story in the new 52 was because they didn't had an original idea and thought it would be more 'superhero-ish' with her gaining cat like powers. That's all.
