An alleged partner presentation slide leaked to the internet reveals quite a bit more about the GeForce GTX 590 than what we already know. To begin with, it lays to rest speculations surrounding the shader configuration, each of the two GF110 GPUs have all 512 CUDA cores enabled. Next, the full width of the memory interface is utilized, giving you 1536 MB per GPU, or 3 GB of total memory on the card.

The rest are fascinating features, such as a removable cooler shroud that lets you clean the card from time to time (you might need to clean it now and then for the best cooling performance), heatsinks that use vapor-chamber technology, getting rid of those pesky heat-pipes, high-grade 12-layer PCB that uses 2 oz copper layers, and a 10-phase VRM (looks like 4+1 phase per GPU). As expected, the final iteration of the card needs to draw power from two 8-pin PCI-E power connectors. "Barely Street Legal"? Is it because they'll throw you out of LAN parties for having too much of a performance advantage? Hmmm.
