I would seriously hope that they are considering releasing some of their own synths as Emulations, particularly the PolyBrute/PB12. I mean realistically they kind of have priced that thing WAY out of the league of most folks, but a software version would make it affordable and enhance it's propogation in the industry PLUS I can tell you as a person who owns the Korg Library, it has helped me make decisions to purchase several of my physical synths having played with the software versions.
Anyway I don't see any lack of material to use to create additional "new synths" but I really do wish they'd hit up their own catalogue. Same goes for Yamaha and several others. Just saying.
