Bryan Singer Confirms 'X-Force' Development, Hints at Female Wolverine

So not only could X-23 appear in The Wolverine sequel, but she might also show up in X-Force.

Bryan Singer basically confirms as much, revealing that not only is Simon Kinberg currently working on a new X-Force screenplay, but that Singer himself pitched a female version of Wolverine — lending credence to recent rumors that X-23 will appear in The Wolverine sequel.

He also notes that the decision to make an R-rated Wolverine sequel was already in place before Deadpool came along.
