I hardly even understand FPGA's but I don't think TI's newest tech will obsolete it. Intel just purchased Altera for $16.7B and I've already seen them release updates to their line including fabrication on 14nm or less.
There's a small customer base that's already used to partitioning their designs across multiple FPGAs, and taking the huge performance hit from it (e.g., ASIC emulation). But for most, yeah... giant PITA.
