The anime does seem to be paying more attention to what went on in the games, the locations and all, but not by much --- they've held off the debuts of Cyrus, Mars, Jupiter, the grunts in general, skipped over the Old Chateau (though I can understand that one), Fantina didn't appear while they were in Hearthome like she did in the games, but I think all those are somewhat trivial.
I think a double battle between Ash/Dawn and two grunts would be interesting. I'm sure Dawn and Ash would work together more now (if I remember correctly, in "The Champ Twins" episode they bickered quite a lot). Them fighting together again is something I'd like to see. I'm also somewhat interested in what Pokémon the grunts have. I think they'll have the same ones as they had in the games, or...did the past evil Team members in the anime have something different? I can't remember that far back.
In any case, Saturn is reappearing in this episode. I'm still hoping for a reference to or appearance by the other commanders, or Cyrus. I think Paul is coming back as well.
