So the good news is x64 is [planned to be] worked on, the bad news is that X-Fi support is possibly not going to happen (ever?!).
That's a real shame about the X-Fi support. Creative (many times unfortunantly, IMO) is the big dog when it comes to PC audio cards and X-Fi is the next generation -- lack of X-Fi support to me, seems to make kX almost a dead end (sorry, no offense, it's Creative's bad, not yours). Hopefully Creative releases the needed specs/documentation!
Are there any pensions/etc. that I could participate in to put the pressure on Creative?
