Having just watched yesterday's stream, it occurred to me that the OP may not have a great grasp of English and that what they are actually saying is that more portraits and 2D art should be included as part of the paid DLC. In the stream, Portugal has no portraits for generals and has the blank 2D sprites for planes, and presumably, for tanks as well. As far as we know there are no new sprites for them either.
It is indeed disappointing if we actually aren't getting any of that stuff as part of the paid content in the DLC, but from a gameplay perspective Portugal's content is looking pretty darn solid, so there's that.
