I can't think of one example of a major studio releasing an English language film in an international market without an English option. (A few Chinese films have been released in Germany without an English friendly option). There is no chance the English soundtrack isn't included. BTW, it appears a less expensive version which omits the 4K disc is also coming.
It sounds like many overthink importing. It's not a big deal, really. You just have to understand that Amazon's listings are incorrect or incomplete much of the time regarding region coding and such, as they are often a cut and paste job from elsewhere. Paramount, Universal and Warner Brothers have never region restricted their discs, but some other studios do. One just has to learn the trends and maybe dig a bit further to get the real scoop.
Funny thing - some of my orders from Amazon UK now ship from Germany, Austria, or Spain, even though the discs are the UK versions.
