A pre-release version has been released to the Kickstarter backers in the past couple of days. I have to admit, there is a lot more here than I thought there would be. Given the volume of materials released to the Kickstarter backers, I have just browsed through it.
The Fate version they are using for this has a few bits from Fate Accelerated Edition (the "skills" are the classic six D&D stats, like FAE approaches), but is still much closer to Fate Core. There is a nice adventure included that I am just browsing through.
I am already running a Fate Eberron campaign, and I am certain I will be using the huge number of NPC's, monsters, etc for that game. I will have to brown through the magic and other special rules to see what else is worth purloining.
