We'd love to, but Lemur has lost steam and we find that most people don't care to use it. We had a blast with Skypad, but for Elysium we decided it was best to add the best experimental Skypad features into the instrument itself. Elysium's mood-based sound generator, for example, came out of Skypad's R&D.
Also the dark side is that it takes a lot more work than it seems, which is probably why other companies don't do it, and we have new ideas that we're excited by that everyone can benefit from, not just tablet users.
That said, we fully support NKS and are adding more NKS features in an upcoming update (mainly switching FX and FX presets, which is proving to push NKS to the extent of its abilities). So if you want hands-on control, you still have a great option.
