I was in the boat of just expecting them to announce the park/name, so I was totally fine with the announcement. (Any nitty gritty details would be not only unrealistic at this time, but could've also dived into Disney Decade Disappointment later on.)
The concept art (while purposely stripped of specific details) looks great, and it's got me looking forward to the future even more!
We're in exciting times as theme park fans, that's for sure.
