I wonder what's up with Rodea: The Sky Soldier. The game's done on Wii, but that's a dead platform so I can understand why Kadokawa would be against releasing it there. However, there was also a 3DS SKU ...
This was on my mind today, bizarrely, it's still shown on Kadokawa's website in the main menu reel, but not in their games section.
Naka should port it to Wii U and just keep the Wiimote controls, hell Sports Connection by Ubisoft actually requires Motion Plus, already a game needs something not in the console box to be played.
So why can't Rodea just have a "Requires the Wii Remote" on the box to work?
Besides, as you noted, a 3DS version existed, so use those controls via the GamePad and the Wiimote for the original Wii controls.
Kadokawa should just suck it up and either ship the Wii version, or allow XSEED to do a NA-exclusive release, or just give Naka enough funding to port it to Wii U so they can release it there.
Or just give back the rights to Naka and let him handle it as he wishes.
