Thanks for posting this! Looks like Warlord for me and priced about where I figured (tho' I know USD will differ a bit). I'm excited that this tier gets me Zeitgeist as well, I've always been intrigued but never picked it up.
To clarify, the Level Up Kickstarter will have the adventure path
ZEITGEIST: The Gears of Revolution as an add-on, but it is available for 5e already. It won't be getting a Level Up-specific release.

The Kickstarter
will have the new
Adventures in ZEITGEIST book, which is a full guide to the setting, and sets up possible future adventures set a generation after The Gears of Revolution.
In fact, we already have the first Level Up adventure out,
Death of the Author, wherein the party comes upon a remote island manor where murder is afoot. There was a Kickstarter for it a couple months ago.
As for Adventures in ZEITGEIST, the new book includes a suite of firearms, items for the setting's industrial technology level, and a variety of new inventions and arcanotechnological magical devices.
There's a new subclass for each class, like the Ravencraft wizards who thieve magic and lay curses, the Gadgeteer fighter who brings an array of Batman-esque devices into battle, or the Queen Bee berserker, who belongs to a high society lodge that
might secretly be run by a psychic hivemind that lets its members share all the rage that builds up from having to deal with the frustrations of the modern day.
(Note: We don't have anything for the Marshal, because the book was developed at the same time as Level Up, and finalized before the Marshal was written).
There are a dozen feats that characters can take to align them with some of the major themes of the world, and for those who are really committed, there is a prestige class for each, including the Applied Astronomist who uses conjunctions of stars to empower their magic, the Steamsuit Pilot who gets to be steampunk Iron Man, and the Urban Empath who can speak to the genius loci of modern metropolises and have the city itself fight alongside them.
There are new monsters, many of which are designed with some manner of exploitable vulnerability, so that combat against them has an element of puzzle, rewarding cleverness.
Plus there's an entirely new class, the Savant, which fills the oft-neglected 'smart person who does not use magic' archetype, for characters ranging from Sherlock Holmes, to Claire from Outlander, to the Doctor from Doctor Who.
I definitely think you should check it out. In fact, you should go to
DriveThruRPG right now, buy Death of the Author, and see if your players can solve the murder before Halloween.
