The hardware is interesting, but it also looks like they've put a lot of effort into programming it. You can approach it from C, or they have a way for you to specify a dataflow and get it mapped onto the hardware. They also appear to have lots of performance analysis tools in their developer kit (which has no price, so I'll just assume 5 figures or vapor).
It isn't aimed at GPU work and it is strange enough not to be a general purpose computer. The obvious hacker markets are password cracking and bitcoin mining, the coins per joule might be a game changer. I'm sure someone on Wall Street can use them to harvest fractional pennies at astounding speed. Low power, high throughput, and big compute sounds about right for an NSA network sniffing appliance. The application will have to be big enough to get someone over the learning curve to justify the strangeness. "Hello World!" won't be hard, but optimizing will be. Something on the Google indexing or Siri scale would be an obvious market if the computation per watt justifies it.
• 16 clusters of 16 processors all tied together with a fast on chip network.
• 32MB of local memory for each cluster.
• Two DDR3 interfaces
• Two 40Gbps ethernet or eight 10Gbps (though I only see two on the diagram).
• Two eight lane PCI Express interfaces
