My predictions: rotation will change very little. Most of EoE is way to slow. Pain-lands will be replaced by Starting Town (more splash enabled because of this too). Shock-lands will replace fast-lands. And vivi-cauldron will get some more bans for reaching 40%. It only loses one sideboard card and only has to swap lands for the rotation.
