Call me Robert guys
I mean they have the right to be disappointed but not the irrational just absurdity that a lot of the comments I'm seeing everywhere seems to have.What I give people the right about complaining for National Dex is that the 1000(+) models obviously require a capable hardware to run smoothly and Switch already offers it.
If you also consider a generation usually last 3-4 years, it is inevitable the hardware will evolve so is the software and make everything possible, and easier, due to the mass growth of technology. If they start modeling the rest of the Pokémon now whether they will be present in SWSH or not, their work force will be as small as the roster of next generation.
I've seen a lot of people being like we can't catch them all anymore which is just wrong because they fail to take into account that Japan never had that slogan in mind and has never used it. That's just something that would added in the west which tbh, I haven't heard in years now from any official source.
