I've been reading through all the threads, and here are a few answers to questions I've seen come up:
RE: Delivery date- We're expecting to ship in the USA in late April.
RE: Drum pattern on sound change- Drum Tracks and KARMA will stop when switching to a different Program or Combi, but without cutting off their note release or effects.
RE: Built-in manual- The HELP button gives you all the documentation for KRONOS, both the the operation and parameter guides, with links to other relevant articles. It's context-sensitive, so chances are it already knows what page you want to see.
RE: Compatibility- With OASYS, It's a one-way street. You can load OASYS .PCG into KRONOS, but not the other way around. M3 .PCG cannot be loaded.
RE: Sequence compatibility- You can load OASYS songs and sequences into KRONOS. If the song contains audio tracks, you need to rename PRELOA_A to PRELOAD_A in Disk Mode, then they should work fine. This is because we now allow longer names in our file system.
RE: Previewing sounds- Programs and Combis can both be previewed in Disk mode, without having to load the banks.
RE: VMT sample playback- The internal 12gb of EXs libraries can be played directly from the internal SSD (with a small amount of information stored in sample RAM), but user samples will need to use sample RAM.
RE: Auto-loading- You can now auto-load .KSC files, including your own samples.
RE: Sample RAM- After loading the entire PRELOAD.KSC, about 273MB are left for user RAM. This is not set in stone, however, since you can pick and choose what you want to use. For example, if you know that you're not going to use the EXS4 Vintage Keyboards library, you can unload it and get more space.
RE: SSD reliability- SSD technology has come so far in such a short amount of time that major computer manufacturers (i.e. Apple) are using them as sock parts on some very popular computers. We, however, are using commercial-grade components, not consumer-grade. In short, we're very confident in the reliability of our drives.
RE: Effects- Additions are present in EP-1, in the form of the SV-1's vintage effects, and the CX-3, where the rotary speaker emulation is built-in without using an effect slot.
RE: Polyphony- Here's the maximum polyphony for each engine:
SGX-1: 100 voices
EP-1: 104 voices
HD-1: 140 voices
AL-1: 80 voices
CX-3: 200 voices
STR-1: 40 voices
MOD-7: 52 voices
MS-20EX: 40 voices
PolysixEX: 180 voices
I misspoke in a few of my demos at NAMM, saying that the MS-20EX was capable of 48 voices. The correct spec is 40 voices. I apologize for any confusion this may have caused. So close to a PS-3300...

RE: Customizing a Set List- There are two tabs in Set list mode, "Play" and "Edit." Among other things, the "Edit" tab gives you large Cut, Copy, Insert, and Paste buttons. Just touch a location, touch Cut or Copy, then touch another location, and touch Paste. If you touch Insert, it will move the selected location (and all after it) ahead one space to make room for the new one.
RE: Aftertouch- Yes, KRONOS has pressure-sensitive channel aftertouch on all three keyboard models.
RE: EXs4 Vintage Keyboards- This includes clavs, reed/tine-based EPs, and acoustic pianos with damper and tailpiece.
RE: EXs5 ROM Expansion 2- This includes tape-based keyboards, percussion instruments, drum kits, sound effects, and prepared pianos.
RE: Scales- KRONOS includes per-program settings, including equal temperment, pure major, pure minor, Arabic, Pythagoras, Werkmeister, Kirnberger, Slendro, Pelog, Stretch, User All Notes, and User Octaves (with 16 customizable slots). Some SGX-1 piano types also inherently use stretch tuning.
Hope this helps.
