Since it's pretty obvious that BDSP will have two-way transfers(seeing as one of the more recent patches added the Legends: Arceus origin mark and a certificate that you unlock by showing an NPC a Pokemon caught in the original Diamond and Pearl), the only Pokemon they REALLY need to worry about adding in are the still missing Gen V-VII Pokemon plus Alolan Ratatta/Raticate/Geodude/Graveler/Golem/Grimer/Muk for everything to have at least one switch title they can be sent to.Dexit thread still going on, eh? *Sees current discussion* Man, I don't even wanna jump into that mess, luckily got some other topic to talk about concerning Dexit.
Well, the new games have been announced and the website essentially hints Dexit is still a thing. There has been plenty of mistakes with Dexit, but now we're about to see whether they're going to make the most damning one.
Here is a list of Pokemon that can't be transferred to Sword & Shield even with the DLCs.
GF, ALL these Pokemon must be available in someway in Scarlet & Violet. I would even say in the main game itself and not waiting for a DLC to add them.
Now, after Gen 9, if they do indeed put all these MIA Pokemon in SV, they don't necessarily need to have a MIA Pokemon appear every other gen. I'm saying they need to do it for SV because Dexit was such a sudden introduction it caught people off guar and felt like even GF weren't completely sure what they were doing. Dexit came with the risk of some of the less popular Pokemon being forgotten. But if they put all the missing Gen VIII Pokemon into SV I'll feel more comfortable with GF handling it so that no Pokemon will be forgotten and give them a leeway of two gens absence. It's not that hard of a task GF, the list is RIGHT THERE. Heck, they don't even need to be catchable in the game, just transferable.
We've already have confirmation of the Flabebe line being in Scalet and Violet, which are among the Pokemon currently unobtainable on a Switch Pokemon game in any way.
