Of course these don't have to be in MM2015, they could be reprinted in other things, like the zen fetches in the upcoming Battle for Zendikar (although I half suspect they'll put the zen fetches into MM2015 so that they can put more pushed landfall cards into BfZ and fit in the creation of enemy manlands more easily).
I'd also note that I'd strongly consider changing the rarity of some of these, perhaps lowering some of the cheaper and less played rares to uncommons, the cheaper and less played mythics to rares, and the cheaper and less played uncommons to commons, while perhaps shifting up some of the better common removal to uncommon. Of course, limited may restrict them from doing so for some things.
