POKEMON SNAP AHHHHH
For the other announcement next month, what do we think the probability is for actual Gen 4 remakes? I'd expect it to be a pretty Big game announcement and not spin-off related at the very least.
I feel like the DLC is being used as the main attraction for 2020 (in the reveal vid it felt heavily implied that they were giving DLC for the regular game rather than a third version), so I'd imagine that if we are getting D/P remakes they'd be 2021. If that is the case - then this is far too early to reveal them.
edit: more thoughts on next weeks announcement
However - for a big announcement I don't think it would just be a spinoff, unless said spinoff was something with an insanely big fan demand, but from what I've seen (which is admittedly limited) I don't think there's anything with that level of demand.
For something that's got a whole presentation for the reveal, I feel like it has to be a mainline game. Even though I said above I don't think we'd get D/P remakes until next year, I wonder if I might have been wrong. I wouldn't have expected them to be pushing another game out before both parts of the DLC for SwSh were out, but I'm kind of doubting that now.
I said it above, the DLC announcement heavily implied that the DLC was being done as a replacement for a third game, so I feel like that pretty much crosses any enhanced SwSh games off the list. Plus it makes no sense to me as to why they'd put out DLC for games if they were already planning enhanced versions (the newer ones would have to be drastically different to be worth it).
although watch me be wrong now I've said that
Also, there's the important matter of the Johto mons in the background during the presentation. Looking at it now, I can see the starters (well Meganium isn't actually visible but I can't see them only putting two of them there), legendaries, Sudowoodo, Ampharos and Politoed. Plus, the Eevee in front of the LGE package has Espeon and Umbreon with it. Normally I don't read too much into these things, but they can be crafty with these little hints. Even though it was said in October I believe that GF aren't planning any more Let's Go games, I wonder if that was intentional to throw us off.
There's also the dark Pikachu which I don't recognise from anywhere. Unless it's just there for aesthetic purposes, maybe that has something to do with it as well.
Now I've written that last paragraph, I think I'm about 70% sure we're getting new games either set in Johto or heavily featuring Johto Pokemon.
