It is indeed intriguing that Aizen is transforming into something so similar to what Tosen looked like when he first donned his mask, when Aizen said he didn't want to Hollowify himself, that's why I said I didn't like the transformation.

Another possibility is that the Hogyoku is covering him in something like a cocoon (and then he will come out with BUTTERFLY WINGS!! -joke!) and when the cocoon breaks he will have reached his "god evolution"? I still think the evolution makes me think of Pokemon (Aizen is Caterpie, now he's going Metapod and he'll come out as Butterfree! -bad joke)

But what really intrigues me are Urahara's words at the beginning of the chapter, when Aizen says Urahara failed to master the Hogyoku and Urahara responds "Unable to master... this is true if you're talking about the past". Maybe the Hogyoku is responding to Urahara's desire and secretly consuming Aizen? Look at me, I'm just making stupid theories here. What can I say, I totally loved this chapter. It's indeed one of the best we've gotten in quite a long time
