The hope for Pokémon Rumble U on the Wii U is that it would take the same ideas but add an HD filter.
Pokémon Rumble Blast on the 3DS ran with the same idea and expanded it, allowing you to collect more Pokémon while giving fans something to play on the go. The toy aesthetic was odd, but the dungeon crawler aspect with immediate action and a restrictive upgrade system made it an interesting alternative to the RPG style of the main series. When Pokémon Rumble debuted on the Wii a few years ago, it was an odd spin-off that had some inherent appeal.
