Nah I doubt that, Shueisha has declared that they're taking this matter very seriously and might suspend future distribution of Watsuki's manga altogether, plus they say there's a possibility the 4th film's going to be cancelled (although that's also partially because the actress that played Kaoru got tebo).
I mean I doubt he'll be in prison for like 40 years as he would be in places like the US on technicalities like "separate counts of purchasing/downloading CP" but his career is probably never going to recover. Not that even the former Kenshin fan in me cares when he's never shown a hint of creativity since around halfway into the Jinchu arc and even his more popular manga after Kenshin were bottom-barrel trash that never passed the 10 volume mark like Busou renkin. Doesn't help that his art is so different now than it was in pre-Jinchu arcs that it looks generic and most of his character writing seems childish rather than possessing some depth as it did in some parts of Kenshin.
