I suppose you might be right, smtg does need to happen, but I hope it will have nothing to do with that Bankai stealing trick.

I think a fight is unavoidable, but I think a lot will come down to the history of the war, as well as both Ishida's and Ichigo's backgrounds. Up until now, it is unknown if Ishida knows more about Ichigo's, so I could imagine a fight would involve that they both try to make sense to one another. Though Ishida's intelligence might be way above Ichigo's, what he may lack over Ichigo is proper resolve: it seems still that he merely joined Yhwach to avenge his mother (being taught by his grandfather Sosoken he must be a bit aware as to why his grandfather was so much opposed to the "new order" Quincy). Ichigo however, has had the choice to be a Shinigami or to be a Quincy, as Isshin told him about his heritage. Ichigo chose to be a Shinigami by heart, and not to neglect his Quincy side. I could imagine the fight would initially start out much like their very first encounter back in Karakura in the first arc. Since they are friends, as well as that they share common grounds (both lost their mothers by Yhwach's hands), I could imagine they will work together in that fight again. I somehow feel that it might be Ishida who will draw the shorter straw deliberately (having nothing to lose but his life, a bit Gin-like if you will, in order to save the greater good).

Having said that, I think both their worlds will shake quite a bit once they (and we) learn Yhwach's proper motives. I still think that both Ishida and Ichigo are beneficial to Yhwach and not just because of some flight up to the Soul Palace. Still on the fence also on whether Yhwach is all that evil.
