@Riot. What will happen to the old Summoner Icons?

Hey, we keep getting cool summoner icons, which is awesome, but next to the new ones the old ones look pretty bad. They are a lot lower quality. Are you replacing them with new ones or will they still be around? The minion- and monster ones could be replaced with the new art, for instance. But there's also the weird ones with trees and stuff. Any plans?

P.S. Even if you keep the old monster/minion icons, I'd love to see the new portraits as summoner icons.
