Battle Boss Blitz Splash Art

When you look at the splash art for Battle Boss Blitz and Arcade Riven both have a bit V.S. with different champs on each side. I was wondering with the update of Arcade Skins if the spots missing on these splash Arts are going to be updated as well. I may just be looking to far into but I find it very fun trying to guess up and coming skins. Any information would be great, Thank you.
