I'm not trying to be argumentative, because it's pretty clear that horse has already left the stables if you're going to be shipping by August.
But ergodox, m15, freestyle, goldtouch are all counterarguments to the theory that "most users" want palm supports for a split tented keyboard. What I want (and based on the market for those products, I'm not alone) is a split tent with a decent layout, just with real switches. I can keep my wrists straight, especially since my forearms are reasonably well supported by my chair arms.
Judging from the profile view at
http://matias.ca/ergopro/pc/resources/images/Negative-TILT-animation_445x100.gif , unless the foam is really tall, people actually resting on the palm support are going to be extending their wrists anyway.
Are the big pieces of foam at least removable from the support?
Again, not trying to be a pain... this is unfortunate, thought it was a good candidate for my next keyboard.
