I really doubt Bandai would import Shurikenjin and try to sell it for $50 to kids. The whole point of the show is to make kids buy the toys, and if the Ninja Star Megazord, or whatever it ends up being called, is too much for them, it defeats the point. The Otomonin are intended to be add-ons to the megazord, not the main focus of the toy line. That's why they appear for a couple of episodes when they first appear, and the leave. So kids pick up the cheaper toy while it's still in their mind. Making them too expensive nixes that market too. Add in the fact that Zord Builder has been running for 6 years now (7 if we count this years stuff), which makes an even better selling point to kids, who love creating and mixing-and-matching, there's little chance they'd remove it just to sell toys that are too expensive.

Bear in mind, this is all my speculation, and I really don't know too much about the market.
