Brownie Brown has discussed possibilities the future, including a possible DS Mother 3 and working on Wii.
According to Siliconera the ever-popular Mother 3 (Earthbound 2) may finally see an official English translation via a version for DS. Brownie Brown lent a hand in developing the GameBoy Advance title, alongside HAL, so a version for DS could be likely. Shinichi Kameoka noted that the project would be due to fans: "If we were asked to make one [a DS version of Mother 3], then we would definitely like for fans abroad to play the game."
Kameoka was also asked on working with Wii and Nintendo's download service, and for both the Tokyo developer is "optimistic about it and looking into it."
Would you embark on a journey with Lucas if Mother 3 were to make it to the West via DS?
