Depends on what one considers a commercial success/what criteria one uses to measure that.
Pokken Tournament DX has apparently sold about 490,000 copies since its release in mid September last year, and sold about 53,000 of those copies within the first week, to throw a few numbers out there to start with.
Is that a success? Are there other things that should be taken into account? I don't know.
