I don't disagree that Nintendo is a better option than ET, but removing ET in the way that's being discussed here would be a completely unprecedented move on Universal's part and is contrary to what the insiders here are telling us anyway. While other attractions have had to make way for newer ones, that's really not what we're talking about here. The ET building takes up a fraction of the space supposedly allocated for Nintendo, and further there is vacant land on the other side if they really need more space.
To follow up on @testtrack321, I'm not exactly following the thought process here.
Unprecedented how?
