I doubt Sakurai and Nintendo will choose to represent a console which has come and past, but isn't yet retro, especially since Sunshine did get fair representation in Brawl, and now Sakurai will probably choose to represent Mario with Galaxy. Representing Sunshine with more stages or characters now seems redundant and wasteful, considering there are many unrepresented Mario games left.Ok, how about shadow Mario represent the game cube for possible (very) new gamers?
I meant Bowser Jr/Shadow Mario, but let me rephrase that, no Mario character will be added to represent the comparatively inferior game. No Mario character will be added to represent any single game (unless Geno somehow manages to get in, but he's in a different situation and another league than Shadow Mario). The Mario characters with decent/good chances (Bowser Jr (by himself), Toad, Paper Mario, and Waluigi) will be added for their contribution to the series in general through multiple games, because in a series as large as Mario, appearing in only one or two games does not equate having good chances for Smash, even as a possible Zelda/Sheik character.No, Junior won't be added to represent a 'comparatively inferior game' as you say, but shadow Mario easily could. Also, as I've said, it's not a comparatively inferior game at all.
And yes, Sunshine is comparatively inferior. Not to say it's a bad game, but critically and commercially it has done worse than every other console main Mario game since SMW, excluding NSMBWii (which did better commercially still).
And as for the "new" thing he could bring the the game (spawning generic enemies), Dedede already does that. Plus what Oasis said.
