Here is a list of all the models that need to be rebased for the 2024 Edition of MESBG:

Do note these are Games Workshop bases, where a 60 mm round base is actually more a 64 mm round base. 25 mm and 40 mm are fairly accurate.

Base size changed:
- Great Eagles get a 60 mm round base (used to have a special transparent plastic base)
- Old metal Treebeard gets a 60 mm round base (used to have a special metal base)
- The Watcher in the Water goes from a 120 mm oval base to a 130 mm round base
- Cave Trolls from 40 mm to 50 mm round base
- Buhrdur from 40 mm to 50 mm round base
- Bolg on Fell Warg from 75 mm oval base to 40 mm round base

Bases for models that didn't have a base before:
- Campfire from Tom, Bill and Bert gets a 80 mm round base
- The Goblin Scribe gets a 60 mm round base
- Isengard Assault Ballista gets a 105x70 mm oval base
- Uruk-hai Demolition Team Bombs get a 25 mm round base
- Mordor War Catapult gets a 120x92 mm oval base
- Iron Hills Dwarf Ballista gets a 100 mm round base
- Bard, Hero of Lake-Town Windlance gets a 50 mm round base
- Gondor Battlecry Trebuchet gets a 120x92 mm oval base
- Mirror of Galadriel gets a 40 mm round base

That's useful, thanks!

I'm slightly annoyed at GW that such a list is needed, though.
