As someone pointed out over in the Rumor Mill, the Gatherer has all 10 of the OGW & SOI simple dual lands listed as part of Amonkhet. Apparently they'll all be included in the set's Deck Builders Toolkit product as commons. Not super earth shattering by any means but helpful for anyone looking for an extra dual land or two in any Pauper EDH decks they may be working on. FYI.
Happy deck building!
