TSR's Super Smash Bros Thread|SWITCH HYPE TRAIN NOW BOARDING

[Lemonray]

Maybe I'm reading too much into this, but this really sounds to me like there are going to be quite a few characters with alternate costumes and voices.

At first one may assume he's just talking about characters like the Villager, Wii Fit Trainer, or Robin. But notice that he says that "even if their NAMES differ". None of these characters have that occur when you change their appearance. And since Lucina didn't get that treatment, I have to assume that their are other characters that do.

This gives me hope for Samus' Super Metroid suit being included. Really, the effort involved would be fairly minimal so there is no excuse if they're giving other characters similar treatment.
I just hope any suits they may include won't end up looking cringeworthy like the Zero Suit Samus design.

There are plenty of other, smaller things they could include too, which wouldn't be difficult or time-consuming. Mirror shields for Link/Toon Link come to mind.
