I wouldn't buy it now while the market is hot, I'd wait for it to cool or for a 2.0. It's by no means a definite, but I'd put it at 50/50. I think there are enough looks to do a second Bane, plus it's a Nolan Batman movie, which HT adores.
I'd like to see an improved 2.0 Bane figure but are there really enough looks for another? I think the clothing with the current Bane nails all the main styles of the film.
