The funding goal looks a little low - I wonder if they're expecting "The community" to do a lot of the software work....
I suspect it could take quite a while (if ever) to reach the sort of standard the notoriously fussy photographic market expects.
There are some videos that purportedly show processed images shot with the alpha version, so some software has to exist already (unless it is all fake, as are most of the pictures - everything is just artist's rendering).
I just don't see how they are going to fund the production of the kit with just $100k and $500/apiece, even though that is just "reservation price" (you have to buy the thing for another $2300 afterwards). Just the FPGA is in the $100/pop range and I don't see the 300fps/4k sensor being that cheap neither. Unless they have a lot of external funding, that leaves very little money for actually paying for the production of the cameras. And I doubt they are going to solder those BGAs in a garage by hand!
Also, if you look at their team, the ones that have actually any info published are people like "new media nerd", "videographer", "3D artist", "new media artist", etc. Not a single engineer in sight.
