"It is realistically difficult to develop new titles and remakes, including sequels, for every Nintendo game that people request, but we are very grateful and appreciate the expectations our fans have for our games."
“We are always considering how to develop new titles and remakes that can be enjoyed by many players."
For what it's worth, it was pretty much expected that nothing was in the works for the series anyways. I'm just wondering now that if Nintendo would be interested in third party developers for the series again. After all, GX was made by Sega's Amusement Vision branch, and directed by Hiroyuki Sakamoto, the same person who works on the Yakuza games.
On a side note, while reading on this, I just found out AMV was also formerly apart of Sega AM4, which was also responsible for the creation of Shining Force 1. If I could ever ask anything at a sega shareholders meeting, I'd ask about if there would be any interest in making a 3d trilogy remake of the original 3 games. But I'm pretty sure the idea wouldn't garner too much interest and never be realized.
