True is 4K across the board no compromises.It just comes down to how you want to define "true" 4K.
I think it's fine to call it that because X was designed to run Microsoft's first party games in 4k. And it looks, at least so far, like that will be the case.
Third party efforts have always been left to those developers design choices. I think Microsoft has been very clear about that.
We get closer than ever with X but not across the board 4K.
If it was possible in all cases then it would happen.
Its not enough for some that the X will be the most powerful console...we have to make believe its even more powerful than it is.
If we don't we are trolling,rinse and repeat.
