I've never seen so many people so willing to draw concrete conclusions from the most vague of concept art, with no actual details given yet...
It was a disappointing announcement, basically aimed squarely at the GP who weren't already aware of what was going on. While y'all argue over imagined details that were never actually confirmed, I'm still over here waiting for the real ones.
I will say that a whole land dedicated to HTTYD sounds completely ridiculous, which is why I refuse to believe it. I'm not thrilled with Fantastic Beasts either, but I believe it simply because Universal is attached to that franchise at the hip. I suspect we will be seeing a more general Dreamworks land when it's all said and done, with mini-lands dedicated to their biggest franchises. Otherwise we know what's getting replaced first.
I'm also hoping this park doesn't open with just 4 lands. I understand wanting to have space left for expansion, but that is overdoing it. A new park should still have 5 lands minimum. Hopefully they just excluded some big things from the concept art because the details are not set in stone yet.
