So i've been thinking about it, and I'm sure dramps will be happy about this, but I don't think there's going to be any dedicated mode for capturing a bunch of Legendary Pokemon.
My thought was two fold:
1. there's an awful lot of stuff left behind at this point pointing to side quests, new features, character interactions, rooms, etc...but nothing very legendary
2. this list of tutorial tips
None of which really align with anything that would be for a mode like Ultra Ride or Dynamax Adventures. Like top to bottom here...
HAGANE -Means Steel. Probably related to the Steel girl. I bet she has a more dedicated sidequest, but probably more on par with Perrin than a whole other mode. I also think if it was more of a mode of play it would be called something other than "STEEL"
RIDEFLY - the new riding minigame/travel mode
TTYPE - likely for the new tera type
SCAN - I would bet this pertains to Perrin's new sidequest
BBPOINT - Explaining how the new currency works
BBMISSION (0-4) - Explaining what to do for the new missions/mini games
CLUB - Explaining the club room and how to mess with it and what you can do
ITEMMACHINE - Bet this is Cram-o-matic 2.0. Put in your garbage, get something more useful. At least it'll be more useful this time with all the exceses materials?
CLUBPC - Presumably anything not directly covered by the Club will go here; probably involves changing the look, items and mayeb inviting people
SMACHINE - I bet this is the "PK Hex lite" we've known is coming.
PHOTOMODE - A New photo thing. Maybe it'll be a rotom drone lol
I
do still think they'll add a bunch of legendary Pokemon to fill the remaining slots, mind you, I just don't think gamefreak will care about letting us get them in the game. They already didn't care about players getting them before the biggest most important worlds, so I think that now that there's a moveset deleter and cross-gen transfers they just no longer see the problem.
Since Enamorus DID get a pokedex stub I think Enamorus will probably still have a way to get her; I'd bet Perrin's sidequest is involved with that. Iffy on if the other 3 would be part of this since they didn't get stubs yet, but they were delayed on carbink (& the unovan starters) too so who knows.
At my most charitable I think these are the only 2 other options:
-They'll release all the legends as part of 7* raids and this will be the thing they run until they stop supporting the game.
-The legends WILL be available in game, but they'll be part of 7* raids that show up in-game (rather than exclusively online) once we're done with Terapagos. I dont think either Black Crystals or the 7* event crystals had tool tips, but even if they did they can just like pop up. Alternatively, they can be part of the "TTYPE" tutorial; we will likely need to get the new tera shard from
somewhere so listing it here could make sense.
but that's a lot of legends to support with the former (in this scenario they would not be as extensive as Mewtwo's was) and the latter just feels like reaching. I suspect 19th type raids will just be added to the 6* pools and you'll have to grind those very slowly, with no legends to go with them.
e: Also I don't think we're getting a battle facility-type mode at all.
