[Let's Go] Anyone remember this old leak?

(Originally from this thread: https://www.pokecommunity.com/showthread.php?t=407367)

Whilst it turns out it wasn't for the 'Core' Gen 8 games which are meant to come out late 2019, it seems it was indeed a real leak - just for the Pokemon Lets Go games (Lets go Eevee to be precise - although I think that this may be a beta version).
I am honestly still in a stupor about this. I seriously believed that this was fake. Does anyone know which part of Kanto this screenshot may be from?

This has to match up with Route 21.

Initially, it just seemed like a rip from Sun & Moon with a few edits but once all the rumours about Eevee started to line up it became somewhat more credible. I just find it funny that they literally had this same shot in the trailer last night which thankfully looks a lot more saturated!

I find it funny that the old thread got locked but it ended up being real lol :P
