How to get Meltan

You can get Meltan the new gen 8 Pokemon by the switch games Pokemon Lets Go Eevee and Pikachu on the switch and it will send a gift to your Pokemon Go account and in that will be a Meltan and maybe some items as well

That's how I understood the two announcements to be.

hoping there will be spcial resurche for meltan i really want him in case (just in case 99% sure its not going to happen) that metagross would get meteor mash as fast move wouldnt get meteor mash or meteor mash would suck metlan is full metal mytical so good stats so i Always have a defensive metal type attacker and attacking of cours

I suspect that anyone who gets the "Let's Go" games will be very popular, because from what I read, anyone can transfer a pokemon to the game (with cooperation from the game owner) and get the box. I anticipate our local raid group figuring out how to set this up so everyone in town can give a "Let's Go" player a gift/transfer/whatever is needed, and get our boxes.
