The new Gundam movie's looking really good.
No, there's no subtitles in this clip and I found no others that did, but you'll be able to infer what's said just fine. The animators earned their paychecks and them some, giving everyone plenty of body language to make that viable and supporting the voice cast's efforts to do likewise with pitch and tone and other subtilties of speech that cross language barriers.
As for when we can realistically expect to get our hands on it, probably by Christmas this year (Officially). Captain Harlock may be able to hook you up earlier, if you're impatient.
