Switch being stable without big releases is great. Maybe it can win August, we will get a good idea with numbers from July.
Also i think y'all are putting too much into the charts for pokemon. Its on a brand new hit console and is the first pokemon in HD. Even US/UM are close to what 7 millions while being only a add on, having backlash and being on a dying console.
The casual market that is the main target for lets go isnt preordering games and probably dont even know its coming yet.
