I feel pretty confident that this will be better than Cars Land for sure. At the end of the day Cars Land is remarkably detailed and immersive, but not to the level of DA because the cast aren't pretending to be cars (maybe they were, but I didn't notice it... Not that it would be very believable anyway). What helps make DA so incredibly special is that every cook, janitor, salesperson, etc. is acting a part. The details and attractions only get you half way. When we walk into SW Land there will be droids roaming the streets. In the cantina you will be served by characters. There will be a level of unprecedented interactivity.
Scott Trowbridge who's leading this project apparently worked on a nifty immersive game at Disneyland in Frontierland all about interactivity. It has gained a group of steady followers. The Pirates that were recently in Adventureland also are testing guest interactivity. The possibilities are really endless. It's taking the idea of being a "Cast Member" to the next level.
All those ideas are being coupled with Robert Iger's most proud legacy item, Star Wars. I feel confidently he'll make this spectacular because this is his most tangible lasting effect on Disneyland and WDW. Not only that, but I see SW being shipped to Disney Resorts globally. Tokyo, Paris, Hong Kong. I thinks they're designing this with a drag and drop approach where it can be placed anywhere. In order for their partners to be interested in approval it has to meet certain quality standards. Which I fully expect it to.
Disney Parks are being asked to do more than ever before to compensate for ESPN's slowdown. What's the perfect way to turbocharge Resorts globally? Build copies of one land at each Resort based on an IP with a wide spread audience. This just makes too much sense.
