This was the assumption from an interview between Kotaku journalist Stephen Totilo and Satoru Iwata. The interview eventually ended up straying off into talking about Mother 3, the sequel to the SNES RPG Earthbound, in which Iwata said there could be a possibility for a Western release.
Here’s the brief segment of the interview between the two:
Stephen Totilo: I would be remiss in not telling you that some of my writers would like to play another Advance Wars and they would someday like to play Mother 3 in America… [Iwata writes something down] … Whenever I ask Reggie about Mother 3, he says, ‘ask Mr. Iwata.’
Satoru Iwata: “Just yesterday, before I left from Japan, I met with Mr. Itoi, who is the creator of the Earthbound series.”
Stephen Totilo: “Oh, I know. Are we ever going to get it?”
Iwata: “And, yeah, accidentally we were discussing that there are huge fans from Western countries for the Mother series.”
Stephen Totilo: “So, someday? Someday?”
Satoru Iwata: “[laughs] Thank you. Great to see you!”
Seems like Iwata doesn’t want to reveal any full details about it just yet. Keep your eyes and ears peeled though, gamers. There’s still that brief chance.
