Momoka and Nina are probably planned for later. But yeah, Sae was going to get a CD sooner or later, it was destined.
Every single time lately I'm surprised by the Passion picks. Like, how is it that Yuko, someone who I haven't seen any fanart of at all (Aiko had the barrel joke going on regarding her measurements, so she's sort of an in-joke like Mizuki is I guess) has a CD while Yui, Yuki, and ESPECIALLY Shizuku don't?
Yeah, Passion does have a tendency to go for Unexpected Characters (TvTropes lingo FTW) when some highly popular characters like the ones you mentioned don't get much. (Wasn't Natalia one of the first to get a Rare card?)
Yuko surprised me on this, to be honest. The rest, I can understand. If I have to try and put a reason in it, I have to guess that the Passion-type is the least popular type in the game, personality-wise. The last election showed how Cool-types dominated the general fanbase opinion, with Cute coming at a far second. Passion-type are probably not that standout among the fans. And since they're following a formula as we've talk about waaay back, Namco must've decided to just give the idols who are popular and interesting enough from the Passion group and give them the CD slots.
That said, I'm expecting they have assigned a well-known seiyuu for Yuko to help in their sales. Personality-wise, Yuko's interesting enough, so it's either they're taking a gamble or there's something the people of this forum missed (and I can't answer that because I dunno too). I'm not saying that everyone else is not as interesting, but like I said, it's a gamble, and Namco placed Yuko on the table.
As for Natalia, they probably haven't found a seiyuu who can do her justice
and/or get her for a fair talent fee.
But hey, that's just a theory.
