I think it's more likely the Triton will get retired and a trickle-down Oasys product is likely...
Mind you, despite OS3 around the corner, it doesn't address the polyphony and dated sound-set of the PA1X, They need to step up working on it's replacement, because the PA800, in several areas blows the PA1X away, and that is never good for sales - to have a less expensive model sound better and be more capable.....
