Here's my prediction of Chapter 416.
Title of chapter 416: Theogonía(Means the birth of gods in greek)
Gin falls down to the ground with his eyes wide open, holding himself trying to stay alive under the pressure of Aizen's enermous Reiatsu
Gin's thoughts: DAMN! His own spiritual pressure is killing me… It's gotten so huge I think even he can't control it now!
Aizen smirks as he grabs the Hogyoku from gin and then preceeds to crush it
Gin: !! Huh? W-why did you do that?
Aizen: I no longer have no need for it's physical form... All of it's power and essence has been stored within me... The fusion is complete now. I am truly one with the hogyoku...
Gin: Dammit... DAMMIT! gin stands up and uses his bankai and Aizen just stops it with his pinky finger and breaks it
Aizen: Hmph... I am beyond everyone else now Gin... You should know that will do nothing to me... * He says while he starts walking away*
Gin: !! Where are you going?!
Aizen: Obviously, I'm going to the ki- before he can even finish his sentence an arrow the size of an car flys right at him and dissolves from his mass spiritual pressure and he looks over to his high right and sees Ryuuken
Ryuuken: You're going nowhere... AIZEN SOUSUKE!!!
Ichigo's eyes open, beind done with his training he looks over to his father and takes a deep breath
Isshin: Yes! You did it Ichigo! Now lets get go-
Ichigo: Father... Wait... This move...
Isshin: Huh?
Ichigo: I can't do it!!!!
