In the latest update to the Kickstarter campaign there's more teasing:
"We’re putting the finishing touches on the tooling for the first version of developer kits now, trying to squeeze in a few key features without delaying, but time is against us. We want to nail down every last detail before announcing anything."
"We can’t show any of the SLAs quite yet (they’d give away a few secrets)..."
[my emphasis]"Thanks for all your support and patience. We’ll let everyone know as soon as more of our details (and surprises) are fully-confirmed. Stay tuned!"
So we know that we're likely to get a slightly higher FoV, but the resolution is unlikely to be changed. What other secret "key features" do you think they're working on?
