Speculation about the next block

After playing some more in the current Standard, I speculate that the next block with be "Kamigawa done right:" An Asian theme (we know this from the names of the sets having a Mongol theme), with tons of legendaries (hint here is the BNG artifact that lords them), heavy tribal flavor which would complement how well Theros is improving on tribal with all those Minotaurs, Sphynxs, and so on, and perhaps an enemy shard theme that would complement Shards of Alara. If the additional 20 slots in M15 are lands, that all together would make for a really fun Standard. As an aside, I very much like how well mono-colored has been done in Theros.
