Take Synchron Percussions I as an example: What you get is good, but compared to former times the Instruments are less. To reach the same amount of Instruments for all Sections will take years and years and years ... (if you see how long it took to finish the first both products, I would not hold my breath here.)
Regarding to Solo Instruments I see the difficulty of the "right placement in the Hall for everybody". Where would this perfect place be for Solo Strings or a Piano?
For the FIlm-Orgel I guess there will be a bigger investment necessary. If I am not wrong the Outputs are placed left and right to the big screen. For us it means that that the sound would come only from the left side.
I hope that there will be "surprises" too. In a hall like this "Epic-Brass-Sections" might have a really big epic sound. Just emagine that there would not only be recordings for Epic Horns this time, but also for Epic Wagner Tubas (8 Players). We all know their Power-Sound from Dimension Brass 2. That would be a Killer!
