Its pretty cool. But at the end of the day it is just a gimmick and I think a lot of developers and player wont care too much about it in the long run. It will not be something that will make consumers change their mind about buying an xbox of ps5.
You may be right in the long run.. But for now its one of the thing that the other dont have.. and I believe many will find it fresh.. but like you said it all depends on how its going to be used the cumming years.
