Leopold FC660M is live, so your wish is granted! It's the new one with dye-sub PBT keycaps, so it's not the same as the older version.

the ducky G2 pro PBT is a very nice keyboard. i have the grey keycap version but would kill for the light grey and white keycaps. Dark grey and blue doesn't do it for me at all though...

Quick update for everyone in this poll, I'm currently working on getting access to some Ducky Keyboards, but I am quite certain we won't be able to get 400 of them (much less the 2000 people that are in this poll). I've talked with Das Keyboard about listing the 4, and they've informed me that July might be a good time to try doing that drop. Keep checking this thread for updates, since as soon as I have em, they will go here.
Just got off the phone with Das Keyboards, they are getting back to me this week and we shall see what they have to say on the topic of answering this poll. I'll post updates here!
I wouldn't mind a Leopold or Topre keyboard (the HHKB was unavailable), but the Cherry switches have a much wider appeal. I've already got too many keyboards as it is, though!
