Maybe Korg have simply learned not to make Ketron's fatal mistake...
Announce a product LONG before it is ready, then announce delay after delay while they try to get it to work right
2011 seems about right for Korg's regular product schedule, personally, I would bet on Q3 or 4 rather than Q1, but I also wouldn't be holding my breath for VSTi's or anything significantly Oasys or Karma based. Korg have yet to leverage the DNC capabilities they brought out in the update (SA capabilities without SA type samples is an utter waste of time, IMO), and all the PA series needs to sound SIGNIFICANTLY better than the PA2 is a good collection of samples specifically recorded to use the DNC engine (and three more fills, at least, IMO
). I believe you can already use DNC sounds in a style, so Yamaha are only JUST catching up to this capability with the T4, and little else needs adding to compete with Yamaha's new arranger.
FLASH RAM would be nice, but I doubt we'll see that until the M series has it. Tyros didn't get it until after MoXF got it, after all...
Korg already leads in the sampler section, guitar section, harmonizer section (I still doubt Yamaha has anything equivalent - without a major rack product, I doubt Yamaha has any significantly NEW technology for pitch transposition... I just see an incremental improvement in their harmonizer), drums and many operational aspects (they still are the only arranger with true WS quality voice editing).
I just don't see the NEED to go in a completely new direction just to compete with an incrementally upgraded T4. If Korg go all out and actually let DNC live up to its' potential by providing it with the samples it needs to show of, that will be enough to make us all sit up and take notice, I think.
