I was at a Triton training seminar on Monday (June 7th). There, we were instructed by Steve McNalley, one of the people responsible for programming the Triton's sounds.
He said the Hard Disk recording option was dropped from the Triton in favour of actual sampling (many of my customers have asked the same thing). People who want to do hard disk audio recording will almost always end up integrating the keyboard with a computer. The development of HDR software has far outstripped the ability to include it a keyboard, especially one that may be on the market for 3 or 4 years.
The Triton will load in Trinity PCG files.
The sound is fantastic. Much warmer than the Trinity, and the added polyphony is a godsend.
P.S. Regarding that weird polyphony (62 note), there are actually 64 oscillators, but 2 notes are reserved for re-sampling, hence the 62.
