@Riot New splash arts, old icons. Will there be more icon updates?

Now that more and more splash updates for those champs with ancient splashes are coming, are you updating spell icons, too?

I know you've said you'll rather focus on re-release scale reworks for those old champs, but there are champs considered healthy even as they are now, needing only graphic update, plus you've already made several icon updates (Shaco, Lux, Gragas, Cho).

Note that there are several champions whose icons still have white circletation borders, pointing the awkward fact they were designed for rounded spell buttons from GUI back from 2009. For example, Warwick's and Evelynn's new slpashes are cool, but those icons with white borders. Ehm...

Also, even though the answer seems ridiculously clear, I'd still wonder whether it is easier (discussing format, color theme, style; actually drawing them) to design and draw splash art or icon art?
