Hi

cheap PCIe is still a problem, a 2 chip solution in price range $20 is
possible
but one chip one is harder

lattice promises 1K$LUT so ECP3-17 should be around 17$
altera has promised arria iiggx as low as 10$

but that the real life is still a little different, yesterday it
looked
that cheapes FPGA with PCIe cost 240$ ? (arria)
hm maybe some virtex is cheaper than arria

maybe s-6 changes this, and becomes first available AND cheap
FPGA with PCIe but it assumed still a year til that
