Wouldn't expect anything more than 2.0 with dragons (and some tweaks) honestly, that's pretty much usually how it goes in these types of games. Maybe a couple new features and systems but those are probably still 6+ months out.
Relic (which is due for 3.1) wasn't mentioned but will probably be similar to 2.x relic with some tweaks.
I think the airship content is something they have been pitching but it honestly just sounds like treasure maps 2.0.
