Yes, really. One only has to look at the hotels Disney is bringing on vs Universal's. One is a locals-heavy park and the other, for all intended purposes, is completely focused on destination tourism. Hell, you still can't get airport transportation through Universal without a full vacation package that includes their meal plan, and even then it's $30-40/person. They're in a totally different league and it's unfair to treat them as such. There is no 1:1 comparison and it's borderline lunacy to view them as equals.
So yes, a JW retheme will do just what it needs to do to get enough of the spotlight during WDWs 50th. It certainly doesn't need to go head to head against it and it's hilarious to suggest that it should.
Again, until park 3 comes online w/ its hotels. Then we can have that conversation.
