Looks like these two are going to be in IF. That Pegasus Knight's outfit is similar to Hinoka's and the background Tharja's Successor is in look likes the buildings of Nohr. Marx wasn't just saying this as a way to get Kamui to return to Nohr.

Another blatant sex appeal character for Nohr, even though they already had one, and still nothing in that regard for Hoshido.

Boobs and edge have already gained innumerable supporters for Nohr. The Hoshido story being easier and having a simpler story have made a lot of people dismiss it. Nintendo needs to give people a reason to side with Hoshido. Two reasons, actually. Two very big, very round reasons. (I'm not saying I'M going to choose my faction or waifu based on sex appeal, but there undeniably plenty of other people who are.)
