I can hardly rank them, as my interest in each and every one of them is too small...
Crown of the Witch (10% chance?) is the only book I might have a remote chance at buying, not because it's Greyhawk (I really don't care about it) but because adventures are always good, and for them whether they are 5.0 or 5.5 doesn't matter. However, I have way too many adventures not yet played, it makes little sense to buy more at this point. Maybe if it turns out to be exceptionally well received.
Dark Sun (5% chance?): in theory, I wanted to give this setting a try for a long time, but this is now too late, as this product will be all about new character material (species, subclasses, backgrounds) for 5.5e which I don't want in my 5e games, and will be slim on actual settings lore like another SCAG or FRPG; so if I really want to try Dark Sun I'm better off getting the setting books from older editions
D&D Beyond: I use it only for quickly checking spell descriptions at the gaming table, and nothing else; if the new features are available for free users then ok, otherwise I am not even going to look at them
Star Wars: never had any interest in a RPG about this in my life... Loved the original movie trilogy, liked the second trilogy, tolerated the third trilogy, but otherwise the franchise is pretty much lame for me at this point.
World of Warcraft: I played the game for a little while when it was fairly new (which is decades ago already) but I have zero interest in running a D&D game in this setting, for me it's another vanilla fantasy setting with no edge.
Icons is probably about fantasy novels, which I don't read.
Classic settings to third parties... similar to Dark Sun, the standard for a setting book will probably be 5.5e crunch and too little lore, so why bother. If they do adventures, chances are better, but again I have too many.
