As long as they keep with the tone and themes in the series it should be fine. I don't mind the format so much as I'm afraid that in the process of "anime"-ifying it they'll completely miss all of the stuff that makes Halo...Halo.

Although I do have to say that the vehicles the spartans are riding in that image look terrible and don't make a whole lot of sense :P.

PS. You guys should watch real hentai instead of this porn stuff.
