You seem very touchy for an honest question.
It seems like Universal's opportunity would be to capture the young family market from Disney, but most of their rides are not height friendly for young children. Having visited the parks with young children, there is limited things they can do and they get bored. Removing kidzone and replacing it with the rumored Nintendo product you describe doesn't sound like it will be very young kid friendly.
While I personally would find Nintendo to be more exciting that woody woodpecker kidzone, will there still be a dedicated kid area? or does this remove even more kid friendly rides?
Also, given all the new IP universal acquired with the DreamWorks acquisition, putting Nintendo in the future 3rd THEME park gate seems like it would give it more space and appeal vs. taking over an existing land (even if that land is outdated)
