No surprise there, we'll see major consolidation in the chip maker market in the near future, with the big 3 (Intel+Altera, ARM+Nvidia, AMD+Xilinx) offering all 3 major types of chips (CPUs, GPUs, and FPGAs).
My bet is that this merger will happen, and then ARM+Nvidia will buy up what's left of the FPGA market (Lattice, etc)
