Fullmetal Alchemist Brotherhood DVD, it would be in English dub right?

Well I can tell you the in the states we are watching brotherhood dubbed, and I think we're on Episode 24. Although I'm not sure how long it would take for them to release that on DVD.

But if you're just wanting to watch it and not necessarily buy it there are plenty of sites that you can do so on. like Adult Swim.

The first DVD you posted was definitely subbed, so you don't want that. But the second MAY be dubbed..it's not even released yet so I could see it being dubbed..I would say that one would be your best bet but maybe you can call their customer service or something? I doubt you would be able to return it..

It'd be in Japanese only because it has just finished airing in Japan. And it takes a while to dub it because they have to reword it so that it matches the mouth movements and so on. So it won't be out in English dub for another year or 2.

Hope this helps!
