The thing is, they don't need to.
7DMT has a line over 120 minutes constantly, and it's 2 years old and from what I've heard, it's a huge let down.
7DMT has all of the MK attractions to compete with, most of which are huge fan faves, but still gets those long lines.
There's nothing in EPCOT anymore other than like 3 tier one rides and maybe 2-5 ok rides in tier 2.
This will have long lines for a very long time, and in disneys eyes, that's a success (unfortunately)
