I agree. Kirby seems too second-tier, so Mario, DK Country, Yoshi's Island, Zelda and Pokemon will get theme park attention before it.
For now, I'm only expecting
Mushroom Kingdom at USF (my guess at attractions: Mario Kart E-ticket, Yoshi's Island E-ticket, DK D-ticket, some sort of flat ride for Wario or Captain Toad, an M&G/show for Peach... it'd also be awesome to see a Camp Jurassic equivalent play area/walkthrough themed to the classic Super Mario Bros levels)
Pokemon at IOA replacing Toon Lagoon and that empty area by Spidey
Zelda in the eventual 4th gate as its own land
Animal Crossing, Metroid, Star Fox and Kirby possibly incorporated as stand-alone attractions in more broadly-focused areas of the eventual 4th gate and/or 5th gate (Animal Crossing/Kirby in woodland/meadow area, Star Fox/Metroid in sci-fi area)
