They will never ship them (expect few close members like Microsoft), because there is no reason for anyone to buy them.
Xilinx already offers more LUTs, more DSP (22 TMACS), 56/112G transceivers, HBM/DDR IP, PCI gen4... So customers who need it already have it available for years.
Best thing Intel can do today is to aim at pushing Falcon to release ASAP but i am afraid that it is late already.
