If this is taking the games as a service route that it sounds like it is, it will surely have emote dances that can be bought with ingame and real money. Probably not the fortnite ones though.
At least in Rocket League it's just ingame movements that you perform. And yeah, I'm sure you're right. Whatever, if the gameplay is fun then it of course isn't a deal breaker. I just still haven't gotten used to all the dancing in games. I'm still having flashbacks from seeing DDR take the scene decades ago.
