That could just be a placeholder cover, for all we know. Knowing Khara, they'd likely tell Madman to use the Amazon dub. If the UK gets the Funimation dub, and the US got Amazon, it'd be like how Funimation kept dubbing DBZ when they took over in the US, while the UK and others got the original Ocean actors returning.
How ironic that would be; the UK, which originally didn't get Funimation's DBZ dub as the standard back then, now has Funimation's Eva dubs as their standard for the first two movies.
No, but seriously, with technology as well advanced as it is today, I really doubt we'd be going back to region-specific dubs. But forgive me if I missed something here. ^^;
