Except where noted:

  • for this first batch, all resolve when they happen or at end 2026 (if this extends for whatever reason, existing answers will be edited to reflect their original dates and new answers will then be subject to the extension)

  • default is to resolve NO rather than N/A

Feel free to add more. Junk answers may be N/A'd as usual.
