Not confirmed, but here it is.
Chapter 316 spoiler --> not a typo
Spoiler (highlight to view)
Let's stop the pendulum.
A night has passed. Urahara wakes up to see Shinji who's face is covered by his mask. Shinji is not moving.
Urahara apologises to Tessai for failing to cure them. Urahara goes outside for some fresh air but is met by the central 46 law enforcement. They are there to arrest him.
He is summoned for interrogation and asked where he was last night. He is asked if he was experimenting on hollowification.
Central 46 suspects that Urahara while in the forrest attempted to use 8 vice captain/captain level shinigami in an evil hollowification experiment. (Perhaps they were told this by Aizen).
Urahara tells them that it was Aizen who did it and that he was simply trying to help them. However Aizen has 124 general shinigami and 1 captain confirm that he wasn't at the scene the night before.
Also, during the investigation there was a report claiming the discovery of hollowification research going on at the 12th division.
Also, Tessai has been sentenced to serve in the third underground prison for using a forbidden technique.
For doing taboo research and experimenting on his fellow shinigami resulting in them being heavily injured, Urahara is sentenced to exile in the living world for eternity.
They then announce that the shinigami who are victims of this experiment will be strictly disposed of as hollows.
When Urahara is about to object Yoruichi who has her face covered by a cloth kidnaps both of them and takes them away to the hiding place near sougyoku.
Yoruichi has already transported the 8 shinigami (vizards) and the new gigai that has been being developed.
After listening to Shinji for a while Urahara decides they are in the worst situation possible and thinks of the best way to deal with it.
Urahara asks Tessai to use Jikantenshi one more time to create a barrier, he will then create 10 gigai for himself, Tessai, Shinji and the rest within 20 hours. Urahara vows to hide himself and spend his time finding a way to get rid of the hollowification.
The scene changes to Shinji and co in the current day.
In the same warehouse, Shinji says that Urahara said there has been no miscalculation and that is the first miscalculation.
He says that everything has come to the worst possible scenario as expected.
Shinji "For real, I am indebted to Urahara.... and then Aizen also."
It finishes with someone saying "let's go" and then the Vizards leave the warehouse.
