We learned in February that the top-notch Wii DK sequel, Donkey Kong Country Returns, will be coming to the 3DS this summer. Now we've learned the developer of the Wii game, Retro Studios, isn't working on the 3DS version.

Instead, the 3DS adaptation is being handled by Monster Games, the same developer that did Pilotwings Resort for the 3DS. The new info comes from the Australian Classification Board, which recently revealed developer details. So what is Retro Studios actually up to? As Joystiq points out, Retro Studios, which formerly worked on the Metroid: Primes, may be working on the previously teased Metroid 3DS game.
