"Pluto Killer" Mike Brown has been tweeting
https://twitter.com/plutokiller about the features observed on the imagery so far - in particular, the equatorial ring of dark spots and the "heart". Interestingly, he points out that such features were PREDICTED in a 1996 paper "Seasonal Nitrogen Cycles on Pluto" by Hansen & Paige

How excited do you reckon those two would be right now that the data is actually starting to come in?!
(By the way - for those unfamiliar with his work, while Mike Brown is mostly known as the guy who got Pluto demoted from full planet status, it's not because he hates Pluto - far from it, he has contributed hugely to the study of the dwarf planets and KBOs etc.)
