I don't know where you got that at, but you are wrong.
There was a Private Press event that covered all this, and they had a 90 min QnA, once again private. At which they released the trailer to us.
Serebeii was at the Press event, where the questions were answered, everything said by them and alot of other media came from the mouth of Masuda.
They are not basing off the trailer, they got a Media Only QnA.
So let's hit ya with some facts.
The game requires a joycon or Gyro to catch.
There is no Online, Battling or Trading, (Local Co Op on 1 switch, battling and trading over WiFi on 2)
There is no Wild Pokemon Battling.
That is all in the QnA, it is all reality. There was a bunch of media people at the QnA, that all made an article, all saying the same thing, from the mouth of Masuda. You may not like the facts, but facts they are.
