If they haven't released a San Andreas Stories by now, i wouldn't be too quick to jump at the idea of one being released. Since R* developed Liberty City as the first game for PS2 and PS3, my guess is they will go ahead and re-invent Vice City next, at least doubling the size of the city. With that in mind, R* took out planes for realism in IV, so i wouldn't think they would be in the next game either. I am looking forward to a new San Andreas though, better graphics, redesigned cities, larger ground coverage, more glitches, and of course, the return of planes.
