Not really sure what you're looking forward to discuss, but these are a few non-edition-specific "big pictures" concepts that come to mind:Basic idea here is discussing the big picture concepts in D&D not pushing specific things unique to one edition.
- multiclassing, or more generally combining PC classes (incl. dual, prestige, gestalt)
- level scaling speed of everything (hp, bonuses, spellcasting, special abilities)
- epic levels, or how/if to continue playing beyond explicit levels
- PC capabilities niche protection vs openness
- combat action economy
- critical successes and failures
- resting and regaining limited resources
- temporary or permanent stat degradation (incl. ability damage, level drain, wounds systems)
- death rules for PCs
- resurrection options
- spells and magic items stacking
- spellcasting disruption and counterspelling
- narratives of magic (e.g. arcane/divine)
- exploration mechanics (loose vs regulated)
- stealth and (in)visibility
- finding traps and hidden objects
- social interaction resolution mechanics
