I'm not suggesting that SNW was never slated for Kidzone. It's clear that the plans were/are for that to happen. I've even said that they could bring the wrecking ball in tomorrow for all we know. I'm just saying that with as much uncertainty has been around the project lately on here(rumors of delays and changes) coupled with the date of the plans suggesting a delay of some sort(even if it was just to revise the engineering), it's not outside the realm of possibility that things have substantially changed. It could be anything from an engineering change to a complete blow up and start over. Theres been suggestions that Osaka's SNW has been delayed based on a lack of progress. If that's also true, that could put them in the timeframe where park 3 is more in the window of practicality. I get wanting to get Mario opened "rightnow". Its a major IP that's not making them any money right now. I'm just future looking and think it just fits so much better in park 3.
As for the Dreamworks IP's, none of them are anchors at this point IMO. 5 years ago Shrek was. Madagascar, KFP, and HTTYD never were huge. Decent midrange IP's, but not anything you tie anything more than a ride to, and all are on their way downhill or past their prime. Trolls is an interesting case as it's got huge merch numbers, I just can't get behind it as an anchor. That might be just personal preference though. But even if you combine all of the Dreamworks IP's into a land, its just a hodgepodge and not an anchor. They aren't going to make any of them as a park weenie. Mario on the other hand can give them that. In USF, Mario will always play second fiddle to Potter.
That all being said, we are on the verge of beating a dead horse with this discussion. We are all entitled to our opinions. At some point, they will start tearing stuff down, or do another press release and we will know. Until then, it's all speculation.
