Here's to hoping I don't get ninjae'd for this, but I happen to have a theory of my own.
So here's the situation... People have been going around, saying that Drampa might actually be the long-deserved evolution of Dunsparce. I've been analyzing the two Pokemon, and it seems that more and more, I find the chance of an evolution chain for Dunsparce being very likely for Sun and Moon.
First of all, take a look at their appearances.
They both have the same color scheme. They're both yellow, white, and green. They are also both serpentine and supposed to be based on dragons (Drampa is literally one, even). Their eyes both don't have pupils either (Well, Dunsparce's only have horizontal slits). However, what makes them similar even more is their wing structure. Look at the tiny wings that Dunsparce has, and then look at the big, majestic wings on Drampa. They almost look like the same, similar structure.
Second, their names. Dunsparce and Drampa have almost the same similar name system as other Pokemon. Kinda like Charmander, Charmeleon, Charizard, or Bulbasaur, Ivysaur, and Venusaur, etc. They both start with the letter D, and also have a "pa" part in their names. But let's take a look at their name origins.
However, while we do not know very much about Drampa, it is said that it may be based on the Chinese Dragon. Two very different dragons, yes, but when we get more details, this part will be much easier to analyze the two.
Third, their typings. People have noted that Dunsparce would likely become a Normal/Dragon type. Now that there IS a Normal/Dragon type that looks similar to it, that possibility has expanded exponentially.
Finally, let's take a look at the ANIME. For quite some time now, an evasive Dunsparce always escapes Ash's reach. What if, this is only one Dunsparce, and not two different ones? What if in the Alola region, Ash finds it again, and this time, actually catches it? Or better yet, what if it evolves into Drampa and actually fights Ash, rather than running away? These are all just possible scenarios, but IF Drampa is Dunsparce's evolution, then that would give a good reason for Ash to continue onward to the Alola region (Even though he really doesn't need to). And if Ash DID catch this Dunsparce, he would actually probably evolve it into Drampa. With Ash slightly becoming more of a badass each and every day, I would think Dunsparce/Drampa would make an excellent addition to Ash's team for the Sun and Moon series.
However, if Drampa is Dunsparce's evolution, then Drampa wouldn't really be a candidate for Psuedo Legendary, but it would make a nice Noivern-like equivalent for 7th gen. Hell, we may actually get the Luvdisc-Alomola treatment again, but with Eevee evolving into Sylveon in 6th gen? We have been overdue several past gen evolutions (I'm looking at you, Jynx and Luvdisc!).
SPEAKING of Luvdisc... What if Gamefreak actually decides to answer our prayers by making a pathway evolution, much like Snorunt and Kirlia? (Then again, since both Alomola and Bruxish look feminine, I wouldn't count on that. If they did, I'd be surprised.)
Looking closely, you can see the heart-shape fin at the end of Bruxish. Anyways, just take a look at those five (We're still talking about Dunsparce and Drampa, don't worry), and tell me what you think. Who knows, maybe Gamefreak might be nice and actually connect Luvdisc and Alomola at least, but who's to say for sure?
