I agree. I was actually very anti-Epic Universe when rumors started to trickle in abut a 3rd UOR park. I'd much rather prefer 2 "maximized parks" with no abandoned areas or lackluster attractions.
But, I don't think Universal will stop with the investments, they know USF needs help. My hope (and I do believe it'll happen), is that USF will see a major transformation in the next few years. I think IOA will receive very little investment.
Nope - Pokemon, as of now is marked for USF in the next few years. The belief is that Luigi's Mansion will be the next mini-land at SNW @ Epic.
So far, most of what will play inside is just a reuse of what's on the site. Merchandise will also go on sale on the UOR merchandise website.
