If you're Nintendo, would you try and have Camelot revive Golden Sun?
The last Golden Sun, Dark Dawn, (which was supposedly the first in the "mainline" series) sold just short of a third of a million units. On the other hand, only two games that I know of were developed by Camelot outsold it, both in the Mario Tennis series.
Or, would you rather have a new IP? (These guys made Shining Force, by the way.)
I WON A BET AGAINST AZUREN! WOOOOOOOOOOAAAAAAAAHHHHHHHHHHHHHHHHHHH
