Thanks for the responses so far, everyone. Feels like we're truly following in the Robin thread's footsteps.
None of this is based off definitive information, but I have some theories.
(1) The sources have seen early development notes and are spitting off the characters from it, even though the Gen VII Pokemon was subject to change (like Chrom).
(2) There's a leaked pic floating around that's planned to be put on the website. It showcases Incineroar as a Pokeball Pokemon.
(3) Upcoming merchandise that may or may not be tied to Smash, such as amiibo, is in the process of getting certified, and the sources connected the dots prematurely (like Shovel Knight).
(4) Bandwagoning. One credible source says Incineroar, the others jump on board because they haven't been wrong yet and they want to keep their streak going.
I could easily find two or three holes in each of these theories, but hopefully this gives us an idea of how Verge's sources could've drawn the wrong conclusion. I don't want to say too much more because it'll sound like straw-grasping, but mistakes can happen. Verge isn't perfect, and what he says is essentially the only thing causing us to believe in Incineroar right now.
1. This is probably our best chance. As Sakurai explained a while back, Chrom and Robin were
both considered early in Smash 4's development, and Chrom got shelved due to feeling too similar to characters we already had while Robin got the all clear because of his ability to do so many things that hadn't been done in Smash before. The way Sakurai explained it makes it seem like they were considered independently of each other, but...who knows, maybe it was a lot easier to drop Chrom part way in because Robin was still there.
A lot of these hearsay leaks come from early development, so maybe this is another example. But would multiple sources all get tripped up in the same way? And would it explain how they all heard of one character who was considered but not another? Though the latter
has happened before; apparently some insider info back during Smash 4 claimed Robin and Bowser Jr. were in, but since that contradicted the at-the-time-airtight Gematsu leaks, none of the insiders took it seriously.
2. A screenshot of a non-playable role being misconstrued is also possible. Especially so if the people who saw it were already presuming it had to be the go-to choice--remember Vergeben mentioning a month and a half ago how if the newcomer wasn't one of the three as per what he'd heard, then he figured it had to be Incineroar "because it's being pushed in marketing/the anime"? Well, we know that isn't actually true.
3. A bit out there since we've never had Pokémon amiibo before, but also not out of the question. What other merch could potentially create a repeat of Shovel Knight?
4. Yeah, also possible, but I doubt we can rely on it as an argument.
It's frustrating, how it seems like most "support" right now is just people jumping on board with whoever the rumors suggest. Conform or be shunned, as it were. If we could just have something happen, some kind of reveal to knock the Litten line out of the running and get people to actually start asking questions...
But something that could support the early pick being incineroar was that with the concept art featuring ash, maybe it was originally going to be the star of the anime, but with the backlash it got, changed to the pokemon that got a lot of attention during Gen 7 hype: Rockruff & Lycanroc.
The only flaw is that Lycanroc was announced before Incineroar was officially shown off, so that could be irrelevant, although didn't Incineroar get leaked before Lycanroc appeared?
I'm not sure there'd have been time to
make a big, sweeping change like that with how complicated production must be. We may have heard all about the leaked concept art, but it only made the rounds among more dedicated fans, just one subset of a very large fanbase. Pacing issues aside, the Alola anime's story arcs seem pretty well structured--if they'd made a change as significant as switching who Ash's ace was for the region, wouldn't you think there'd be more signs of it? Like how the Unova anime was so shaken up due to cutting an important story arc after the earthquake happened?
By the way,
Maikou
, mind if I add those taunts and victory animations to the front page?
