Between Cars land and Villains Land, there will be a very significant increase in park capacity. The Island was basically dead, and the Riverboat wasn't close to full on non busy days, plus it seemed it was down for refurb about as often as it ran. This will help to distribute the crowds of Fantasy land into this area. There will be so much more to do and explore at MK when these are completed. Like most, I'll miss the waterway ambiance. But if these lands meet the thematic levels we've seen in the various new lands at Disney Tokyo, that might be enough to make up for losing the rivers look. Myself, I'm very pleased with these new lands, plus they're both fun IP's. Sometimes you have to let nostalgia go, especially when it's become stale.
