The TLDR is that OAK-D was a hit.  Folks love the capabilities, and it makes solving all sorts of problems WAY easier.  It is the cheat mode for interacting with the world that we thought it would be.

But... it is too expensive for many (most?) applications.  

So we started from the ground up to make something that had all the power of OAK-D, but was low-enough cost that folks no longer had to say "Man, I sure wish I could use that... but it's just too expensive".

We can't say how much it will cost just yet, but we can say that the first 74 backers will get a special deal.  ;-)

Oh and also other applications were blocked by the size and weight of OAK-D.  So it's also a bunch smaller and lighter (as the name alludes).  

Teaser below:

My wife found a golf ball that said gold.  So we used it as a reference, pointed at the gift box for OAK-D-Lite.

The gift box, with OAK-D-Lite tucked nicely inside, is actually smaller than OAK-D by itself:

And here is the comparison of the gift boxes for OAK-D-Lite (front) compared to OAK-D (back):
