Making an ASIC with pedestrian low speed IOs is easy. Making an ASIC with high speed SERDES IOs that are required for PCIe is hard.
Also, AHA has a followup product that doubles the performance by dropping 4 ASICs and 1 FPGA on a board instead of 2 ASICs. So modularity is a factor as well.
But I think the first point is very likely the reason.
