Since we're all put in the position of speculating, why not have fun?
Here goes ...
I think it's going to be the Choir with a very interesting new Performance Tool and the "Vocal Tool" that allows you to enter text and, voila, the proper phonemes and transitional sounds will be automatically stitched together ... resulting in the choir being able to actually speak! No more only "ooohs" and "blaaahs" from sample choirs.
Or, maybe it's the newly redesigned Performanc Tool (called "Dynamic Tool") + Symphonic Cube. The new tool automatically detects crescendo and diminuendo in a sequence (and knows its length) inserting just the right dynamic sample to match. Magically, it also works in real time.
