Ships? Don't know where you got that. Dragons? Already got one, and we all want more. But let's remember, it is possible that we will get them; mesa seems like a very dragonish place to me, and one of the snapshots depicts a little alcove in the side of a mountain in a mesa. In the cave? An item that looks suspiciously like a dragon egg. So who knows, dragons could be arriving in 1.7.
And krakens. Never forget the krakens. I believe notch originally said red dragons would hatch from dragon eggs if they were added... Assuming jeb does this, you won't have to fight it.
OMG, cannot wait for that, seriously been wanting stained glass for a very long time hahha. Woohoo !!
There are still things to do before dragon tombs. Odds are 1.7 will be on EMC when dragon tombs is halfway done
