The question asked was, as far as I understood, about turbulence and not continuous distortion/torsion etc. 

Since no wing is 100% rigid in turbulence, it's impossible to tell the difference in behavior/handling, in the real aircraft and in the sim and I doubt that would be possible to precisely calculate where the difference e.g. in severe turbulence actually comes from.

I'm quite sure that we will e.g. not see actual opposite wing bending due to aileron deflection in the new sim, but it should be easy to simulate it and hopefully not (only) q dependent.

There are many technical papers that deal with gust response for an elastic wing, so there is at least some influence. Although as you suggest, it may not be particularly significant to model in a sim.

In my opinion, aeroelasticity effects due to high speed are more important to model, e.g. decrease in pitch stability, decrease in control effectiveness, aileron reversal, etc. These can be simulated with tables in a table based FM, but require different hacks in a finite element FM (XP or FS2020), and is maybe more complex to do.

AFAIK, AFS2 uses fully elastic elements for its flight model, so in theory it should be capable of natively modeling aeroelastic phenomena. Maybe in the future FS2020 will introduce elasticity in its flight model. After all, they already rewrote the ground physics model, and as I understand, Sebastian Wloch should be an expert in physics.

Thank you both for excellent answers to my question. 

A noticable difference in perception exists IRL between airliners with wing mounted and tail mounted engines. Since aircraft with tail mounted engines have much stiffer wings, turbulence feels noticeable stiffer/harder in aircraft like e.g. MD-80s.
