Year 1, agree. Having expansion directly in site in opening year suggests it was an incomplete park. Year 2 is fine, it shows commitment to upgrading year after year.
I'd rather Pokemon come to Universal Studios instead (Kidzone). There's a ton of *Mario* related content they could still add at EU. Smash Bros show, Luigi's Mansion dark ride, and a Pikmin dark ride, each with supporting immersive land, would be more than enough to fill in that space.
