Jeez. It's not even out everywhere and you already clamor for other theaters. Keywords:
finger,
take,
whole arm with shoulder 
My personal and totally unprepresentative list in no particular order:
- Fix of performance issues
- Fix of translation bugs in GUI
- Bf 109 E-1 and E-4 (as talked about by Luthier)
- MG FF/M for Bf 110 C-4 and C-7 (as in reality)
- skin templates for all aircraft with 3D overlay
- Fix of marking issues (falsely assigned emblems, units in wrong category, ground vehicle markings not working)
- AI Ju 52
- warships
- Those gorgeous human figures we've seen in development (tank, vehicle and artillery crews, mechanics etc)
And last but not least ... some detailed documentation about the FMB.
