I'm personally not expecting that many additions to the Shinou Zukan (Pokedex) other than possibly Pokemon like Nymphia (Sylveon) depending on the circumstances and possibly regional variants from other games, although the latter might be post-game exclusive. I still don't know what to expect with regards to which Shinou Zukan they'll use in these games, however. My gut tells me that it'll be the D/P one just for the sake of consistency with the original games.
