I don't think that a majority of the Japenese talent that's exploding on the contest scene right now will have much success in the realm of legitimate street skating. They're extremely talented and do fucked up technical tricks, but I'm not sure if they'll break out of the TF.
If you judge success as having a unique style/trick selection and skating interesting spots in creative ways, then yeah, probably not.
But if you’re talking about grinding out just enough footage to appease their energy drink overlords and keep the fat checks rolling in, then yes, they probably will be successful.
Or maybe they’ll just tell us all to go fuck ourselves and won’t even bother to film any street stuff.
