Nah, Ishibumi said the future wives (in DxD) are already mostly fixed. Probably won't be adding anymore in DxD itself.

As for the tournament, i really doubt Ishibumi will write too much on it, since he'll have to think a lot on the match-ups etc, so he'll probably try to cut it short and end it without going to far.
