Lol... That's weird, did Chronobound look up more info and find that Dixie has more requests now?
What Gamestop hoax?
Well, moveset potential is a good reason, as is a new franchise. However, with Sakurai's statements, it would rely heavily on Custom Robo getting a new game, and based on the fact that the franchise sales are mediocre and there hasn't been a game since before Brawl, that doesn't seem likely at all...
Of course you disagree on GS, but GS is definitely more likely to have a new game in development right now, the first two games sold way better, and Isaac is far more requested in general than Custom Robo. Plus, GS1/2 are actually being added to the eShop, which Custom Robo doesn't even have at this point.
The other odd thing about GS is that there has been a GS game since Brawl. Even though it didn't sell well, its not something that should force Sakurai to drop all references to the franchise all-together. Custom Robo, on the other hand, hasn't had a new game since before Brawl, in fact, the franchise was much more "recent" in both Melee and Brawl.
