I actually don't think so. We don't call The Empire Strikes Back "Episode V," or Return of the Jedi "Episode VI."
In fact, the only reason I think people still call the prequels "Episode I" and so on is because the "Episode _" was so prominent in the advertising. Based on the title treatment released today, I don't think we'll see "Episode VII" much, if at all, on posters and trailers and the like.
