The text says that Hogun decides to stay with his family after the first battle, while Sif, Volstagg and Fandral go back to Asgard. He isn't in the funeral scene, in fact.
Do you think that might mean we'll see little of him, compared to the other characters I listed above? That would explain why we haven't got a solo poster for Hogun. It would be a bummer, though.

Awww, no. That would really suck if his role is smaller than even in the first film.

The fact that he isn't in Asgard for the funeral wouldn't have worried me because the junior book only covers the first part of the film, but the fact that he was singled out in the promotion compared to Volstagg and Fandral makes me think. The only other main players who didn't get posters are Kurse and Frigga, and they both are likely to die - that doesn't help, either.

Alan Taylor said he wanted to give each Warrior Three (+ Sif) focus on their own instead than just as a group, but if Hogun gets like, 2 scenes and that's it, I'm going to be pissed anyway.

Fingers crossed he travels back to Asgard around the middle of the movie.
