I guess FPGA tech moves pretty slowly.

It is remarkable how difficult it is to establish a new FPGA company. I'd say Achronix seems to be doing well, but even they had to pivot from their origin (async FPGAs)
Actel->Microsemi->Microchip is still going. Their PolarFire FPGAs are competitive with Lattice for sure, seem to have better MIPI support than Crosslink.
They had some manufacturing agreement with Intel, but I have no idea if anything came out of it.
