I was reading another thread about how people seem to think that Disney is losing ground to Universal based on the IoA/US thrill ride theme. If Disney decided to build a 5th gate that would cater to the thrill ride crowd, while still keeping the Disney themed experience, would that put an end to the whole IoA and US debate? I personally have been to both parks and found them to be very cool, but not a place you could spend more than a few days at. Our next trip to WDW is in December and is for 9 days and we still won't be able to see everything.
