Having done a lot of remixing of Phandelver myself I will definitely be interesting in looking at the official version. Buying is a whole different matter. Even setting thoughts of boycott aside I've been generally unimpressed with my WotC full-book campaign purchases, and had all but sworn them off.
WotC books have never been the strongest supplements and adventures in service of 5E. I might have bought Keys and Phandelver out of curiosity before the current Mess, but now it's nothing. Never again.
I'm looking forward to the Phandelvar book. I have made several campaigns based around that area and would like to add more. Not sure how much is the box set and how much is new material to extend the campaign though.
I'm afraid that I'm setting myself up for disappointment.
Phandelver, cuz I like Phandelver and like campaigns. Giants no, cuz well, honestly giants have never sparked my interest. And I've already bought 3PP stuff for magic items, spells and NPCs so not sure I need more than the hundreds I already have.
After looking up each of the releases I'm not particularly interested in any of them. Each one has pieces that I would like to check out, but that's not really enough anymore. I need something that has more of a wow factor or game changer.
Keys From The Golden Vault isn't my normal type of book, but I was intrigued by a book of individual adventures with a common theme. Even if I wouldn't run the adventures it could be a great resource to run my own heist adventures. The fact that it is a perfect tie-in with the upcoming dnd movie also featuring a heist was almost enough to sell me on a purchase.
Sales for that book will be very telling of the impact of the OGL stuff.
Keys from the Golden Vault blurb says there is a "heist at the center of every tale". After Dragon Heist wasn't very heist-y I hope I'm not hasty in saying "fool me once..." to this one.
Glory of the Giants - maybe
The Book of Many Things - no. I've never really been interested in the Deck of Many Things so a book about it doesn't appeal to me.
Phandelver Campaign - no. I haven't been fond of Hasbro's 5e campaign books. I loved Lost Mines of Phandelver and think it's an A+ adventure. But not the longer campaigns.
Planescape - no. I wasn't particularly interested in Planescape when it debuted for 2e. I like that it exists. I bought some of the 2e pdfs from DMs Guild on sale a few years ago. But I have no real desire to get a 5e book of it when I'm never going to run any adventures using it.
So I guess that leaves one "maybe". But with Hasbro's behavior recently it's really a hard "no".
I think the main thing that has me less interested in getting more books is that with the changes to OneDnD, any player options that come out in books this year are likely to be out of date as soon as OneDnD comes out if they're something like subclasses.
I’m curious about Planescape and Phandelver, but 5e Spelljammer has set my hopes pretty low for Planescape, and their intentional shift to adventures made in small chunks makes me dubious about Phandelver.
Plus, the general Wizards fiasco.
It may be a pretty cheap year for me! Probably just a couple Kickstarters: Kobold and Goodman… and some unexpected surprise or another.
