I posted earlier saying I wouldn't be buying any due to the OGL situation, but now that WotC has reversed course I will probably look at purchasing all of these.
Top of the list for me is the Phandelver campaign. I really like Lost Mines and Dragons of Icespire Peak, so am very interested to see how they expand it. Specifically, I like the idea of saving a small town and having it be a home base and a place you fight for, build relationships in, and ultimately have a vested interest in. I think Lost Mines especially had lots of good hooks, so I am curious to see if it is expanding on those, or an all new adventure surrounding the location.
The others are all in a general interest place for me. I'm always happy for more content that expands on lore, provides new monsters, and provides interesting mechanics. None of the titles stand out as must-haves that I couldn't live without, but they all seem like interesting additions to my DM'ing arsenal.
