What's the point of the sequwl about Wolverine?

I've read that there's an X-Men film called X-Men: The Wolverine coming out next year, but I really don't understand why. We now know the backstory of Wolverine & know that how he got those metal claws. And most people didn't even like that film; it was a failour, so why are they making a sequel? What's the point?

Because it made twice it's budget at the box office, really.

Because a better crew is on board and because we'll get to see Yuko on the big screen. Too bad there won't be a punk rock Storm though...

Also read for "The Wolverine" it won't have anything to do with the first wolverine movie attempt

Hugh Jackman says it

Too bad Jackman is playing Wolverine.
