There's going to be a new series of workstations that replace the Triton series. This new workstation line is reported to use the same HD sound engine as the Oasys but will lack many of the features of the Oasys (obviously for good reason). It should be interesting.
The Oasys is also reported to have some new updates on the front. Hopefully Korg will greatly impove the sequencer, hard disk recorder, and add cue list as well. In addition it would be nice if the Oasys could import and play Giga and Kontakt files and further simplify the GUI.
NAMM will certainly show us what Korg's devotion to the Oasys is going to be. It had better be damned good or many of us Oasys owners wil most likely ditch the platform altogether. I know I'm on the fence right now.
