I am hoping to pick up another Kronos in August. I'm finding that as a gigging musician who also does a lot of studio work that two of these instruments plus either the Jupiter 80 I own or if I can find a good deal on a V-Synth GT will cover a hell of a lot of sonic ground. The Kronos I have now came with me from the United States and its two year warranty has just expired in May so I am completely comfortable doing the memory upgrade myself. If I can find a non X Kronos here in Holland - and I have seen quite a few, I will get one of those and again wait for the warranty to expire especially since the first Kronos will already be a X for all intents and purposes.
I have to say that Kronos is so powerful that except for the memory upgrade to be able to stream samples, there are virtually infinite possibilities with the instrument as is. And worse case scenario if Korg only offers updates for the Kronos X, the original Kronos is still far more than I could ever master in a lifetime. Furthermore, OASYS musicians are making great music and still discovering new territory for their instruments and there seems to be no "upgrades" in sight for OASYS and that hasn't stopped these musicians.
Laugh if you want, but, I am still amazed by the "older" keyboards I have too. The Fantom X, Kurz PC3, Motif ES, Radias, and even the venerable XV-88 provide me with stunning sounds that are musically useful on stage and in the studio.
A Kronos X isn't "better" than a Kronos at this point, but it begs the question of how to define better anyhow. Just because something is improved upon does not make you a better musician - but you already know that.
Perhaps not the best comparison, but, what the hell: how about an 88 note polyphony instrument that has "one" patch. Do you find that interesting? A good one will cost more than 3-4 Kronoses and the best of these one patch instruments would cost as much as a studio full of Kronoses.

Current gear: Kronos, Jupiter 80, Kurzweil PC3,Roland Fantom X8, Roland XV-88 (yep, its old, but the ACTION is heaven and those XV-3080 sounds are still wonderful for me), Radias-R, Motif ES (yeah it's older but I love the guitars

)
