For me, it's the return of the international CMs to World Showcase. I still enjoy it and all the CMs currently working there (largely College Program) are doing a fantastic job but to me there's just something missing without the native CMs in each pavilion. I always liked practicing my very limited knowledge of different languages, hearing about where they're from, and what they're enjoying about the US. Would also like to see the various pavilion stores fully stocked and all open.
On a restaurant note, anxiously awaiting Jiko and Flying Fish.
