I actually am surprised that we do not have this yet. I would assume that whenever the JU87 gets updated that this model will be included.
The reason I believe this is that we've just seen the P40 updated, and different models added. At the same time we received updated Panzer IV and three different versions. And earlier, the Mossie was updated, and soon after a different model came out, as well as the M3, when updated that had a new version.
I believe that the going trend now is that when something gets added, or updated, the most logical sense being to get the biggest bang for your buck. (i.e include the varations) This further makes sense to me in that I would suspect it is getting harder and harder to include new aircraft due to more complex modeling of the aircraft, and the probable rariety of data to recreat a new aircraft that we do not have. (iar.80 for example...anyone have those blueprints?)
^yeah I know I kinda went off on a tangent there
