Thanks to Penguin Random House we have some more information about the first Korra comic.  We get the full exact title for the first book, a slightly updated product description as well as a date.

First of all the listing calls the book "Legend of Korra: Turf Wars Book One". This is interesting as the ATLA comics call each book Part 1, Part 2 and so on. This seems to be suggesting that for Korra each part will be called Book 1, Book 2 and Book 3. It could just be some odd wording on an early solicit, but it seems like they want to very much make it clear that the Korra comics and the ATLA comics are different series by calling each edition something different, Part for ATLA and Book for Korra. Second is the description.
Relishing their newfound feelings for each other, Korra and Asami leave the Spirit World . . . but find nothing in Republic City but political hijinks and human vs. spirit conflict! A pompous developer plans to turn the new spirit portal into an amusement park, potentially severing an already tumultuous connection with the spirits. What’s more, the triads have realigned and are in a brutal all-out brawl at the city’s borders–where hundreds of evacuees have relocated! In order to get through it all, Korra and Asami vow to look out for each other–but first, they’ve got to get better at being a team and a couple! Written by series co-creator Michael Dante DiMartino and drawn by Irene Koh (T.M.N.T., Sensation Comics featuring Wonder Woman, Secret Origins: Batgirl, Afrina and the Glass Coffin) and with consultation by Bryan Konietzko, this is the official continuation of The Legend of Korra!
This is only slightly different to the description we have seen before, the new parts are marked in bold here. It is just a minor change, but it seems to be a change to further emphasise that this book will give strong development to Korrasami. The last and most important piece of news would be the release date. Previously we knew June 2017, but no exact date. This listing says June 20th 2017. This is a Tuesday and comics come out on a Wednesday so the 20th will not be the initial comic store date. Based on previous experience we go back 13 days to get the proper release date, this would give us June 7th 2017 as the comic store release date. So very early in June, this is good as it means less waiting. The only thing I would add is that this is a very advanced solicitation, so the date could change, but Penguin have been correct with these things before. Thoughts on this new information?
