Yhwach claim about Ichigo battles and growth were because of him, makes sense, after all he is the creator of the Quincies, anything they have done is because of him, in fact if it wasn't for Yhwach Ichigo wouldn't have been born, if Maskai wasn't a Quincy, she wouldn't have meet and save Isshin, and we wouldn't have Ichigo.

As for Ichigo vs Uryu, I think it might end as either a lose for Ichigo or a stalemate, I think we will get a glimpse of Uryus new power, and besides any of Ichigos potential rivals have always have more than one match, e.g. Renji, Byakyua, Grimmjow, Ulquiorra and Ginjo.
