And some of them got ported to PS3 with extra content because they sold like garbage on the Xbox 360, like Eternal Sonata, Star Ocean IV, & Tales of Vesperia (Japan only, though).
Not like they set the sales charts on fire on the PS3 either. TOV being the only really good JRPG out of the third party games. Infinite Undiscovery Blue Dragon and LO were owned by MS.
It's pretty obvious what Scalebound is. It's Bayonetta / Revengeance but with massive fights (Dragons). I'm sure it'll have some big unprecedented boss fights for a platinum game that'll make fans pretty happy...and everyone else yawn.
A JRPG it is not.
Just because Kamiya is directing it doesn't mean it will be anything like Bayonetta, he has a fairly diverse catalog of games he's worked on.
When it fits the narrative, you gotta, man.
I keep forgetting that.
