Sorry but i don't see why spam dislike or angry comment will help much, it could be have better effect if someone in E3 find Matsuda, jump on him and shout right in his face or and try to attack him with your anger something like that but don't do that for the god sake or have fun in jail.
My point is they are not idiot, theh should know how this going to upset and still told us now anyway, even from now the comment in YT and Twitter will be full of angry fans, like they going to care?
I mean i just saw Pokemon tweet about Go and then the comment gone wild as i expected.
...Oh i just notice this, Remember when people angry that Mario Maker 2 won't allow you to play online with friend and now they changed it, then some fans will think "Hey! It worked!" and then going to do the same with Pokemon Sword and Shield too, man...this is going to be long ride, isn't it?
It would be funny if the game release and datamine found all Pokemon models in the game just like all walking animation for Gen 7 lol...but it not seem to be the case.
