Might as well re-post here:

Stranger of Sword City Vita selling out; digital sales are strong.
It's Experience Inc.'s first self-published game on the console and seems to be doing well past expectations. They might only have the capacity to print enough copies for the sales they reached on 360 (~10k LTD), so I'd imagine they're a bit more hamstrung on Vita where all their titles have sold well past that.
Anyway, good news!
