To be fair, I never said "nothing came out during that time", so I'm not entirely sure where you got that quote from.
My point isn't so much that they won't look at Wii U stuff, I'm sure they will on the contrary. I simply believe that Nintendo, as a company, would want to shift the focus of Smash on successes or get on the hype train of the Switch.
Given the fact that Sakurai is NOT a Nintendo employee, I can totally see Kimishima suggesting that he look at SOME content making it to the Switch. Again, but no means do I believe nothing from the Wii U will be in the game. From my recollection, however, a lot of the titles would simply support similar series.
For example, from those lists that other users are sharing, I immediately consider Captain Toad, Dixie Kong, Elma, and Bandanna Dee. We already have Inklings, so it's a given that Wii U games are going to get characters, stages, etc.
My argument is simply that I think early Switch titles could get playable characters as well.
I've gone over numerous times in the past why I think it could be different this time. Not only did this game start development after the previous title, but it was developed during a pivotal time in Nintendo's business strategy/their future.
I firmly believe that Kimishima discussed with Sakurai the opportunity to create another Smash game to propel the upcoming console even further, especially considering the power of Smash. Contrary to popular belief, Sakurai is NOT a Nintendo employee, so the idea that Kimishima would chat with him about the new game isn't entirely out of the question.
The Wii U, the console generation in its entirety, has been a low point for Nintendo. It's close to the Virtual Boy in terms of success. Or lack thereof rather.
I'm also not saying he would ignore the entire generation. There were some gems there. But I'm not sure it's enough for a completely compelling group of newcomers.
I could be reading this wrong, but i'm detecting a wee bit of aggression, and I'm not really sure why?
Porting games from the Wii U is not to "remember the Wii U". It's to bring their top titles that, frankly, a large group of potential customers never played because they didn't play the Wii U. That strategy has worked. They're not stupid enough to "forget the Wii U" by not capitalizing on an opportunity to make money.
I also think it's obvious that anything Zelda will by default be larger than a newer IP. That's obvious. If we base everything on that, however, we'd be getting characters from the same series in every Smash title. I think new IPs and the growth of an existing IPs are equally important, but in different ways. To assume BOTW is way more important than putting out new games for other series seems a bit like a leap. Did it perform better? Yes. It's a brand new, open world Zelda. Of course it would perform better than a JRPG sequel (that became the best selling in its series) and a new fighting IP. How that translates to Smash, however, may not reflect that.
In terms of Xenoblade, I don't think it's that simple. Elma could get added, and I'm sure she'll be loads of fun. However, given the time of roster selection, Monolith had been working on XC2 for at least a year or more. The game was scheduled for 2017, and if Sakurai was looking for a newcomer from the series, he WOULD have the option between the two. Just because he could just add Elma doesn't mean that that's what he would go with.
Lastly, if we're talking about amiibo as indicators of likelihood, then I guess Tiki, Chrom, Toon Zelda, Chibi-Robo, Daisy, Waluigi, Boo, Alm, Celica, and a crap ton of Animal Crossing characters have a chance. To me, that doesn't mean much.
