Also, it was made with the help of the Oriental Land Company so we'll probably never see a park like that come here unless they pair up with another companyThe US will never get anything as cool as Disney Sea. Why? Answer, because Disney does not need to, guests will mob the US parks no matter what Disney does or does not do there.
That said, I am looking forward to experiencing all the new stuff at WDW. The down side, as always, the mobs of people at WDW will be worse than ever!
