Retro Studios recently completed development on and released Donkey Kong Country: Tropical Freeze. The developer has yet to announce their next move, but they have confirmed (via GameSpot) that they’ve got a new Wii U title in the works and that production began after development on Tropical Freeze was completed in November. However, Retro’s President and CEO, Michael Kelbaugh, couldn’t reveal any specifics about the unannounced game. And he purposely attempted to downplay its identity by stating how fun all of the company’s previous projects were:

“We love working with Donkey Kong. It’s a great character. It’s a lot of fun. We love working with Metroid Prime, with Mario Kart; those are fun, fun games to work on. So, you know, you can’t lose,” he said. “Every one of those IPs have been a lot of fun to play with and work on and [we’d] love to come back to them sometime.”

So is Retro working on the oft-rumored Metroid Prime 4/next Metroid game? Or perhaps that “American Legend of Zelda” is more than just wishful thinking. There’s even the possibility that they’re helping put a last-minute shine on Mario Kart 8. Whatever Retro’s next project is, Kelbaugh sees a lot of untapped potential in the Wii U and believes the system is a “powerhouse”:

“Unfortunately, the perception is that it’s not a very powerful machine,” Kelbaugh said about the Wii U. “That’s just not true. It’s a powerhouse. It’s more than adequate to make great games on.”

With any luck, Retro’s next game will hopefully be announced at this year’s E3 Expo.
