Has anybody even announced a FW3200 device, let alone a FW3200 controller? USB 3.0 will lock up the market by virtue of universal penetration, aided by Intel's decision to have no FW support on its standard chipsets. No, FireWire is walking dead. I guarantee FW16/3200 will never see the light of day. I was at MicroCenter the other day and they had many USB 3.0 and USB/eSATA external enclosures on display, but not a single FireWire one. It wouldn't surprise me if most of the customers there didn't even know what FireWire was and had never seen a FireWire device.
Mark my words, Light Peak will never be anything but vaporware. HDMI device manufacturers have spent too much money pushing the technical disaster that is HDMI to get consumers to switch to an interconnect that obsoletes all their hardware. Ethernet over copper is good to at least 10G using Cat6. SATA 6Gb is already here. There is simply no use case for Light Peak no matter its technical merit.
Never forget that USB is an Intel standard. I bet the FW consortium realized FW3200 was already DOA and there was no point in developing any products based on it. How was the FW consortium to get Intel to include FW3200 support, when Intel wouldn't use FW400 and instead went with the grossly inferior USB2, using its near-monopoly position to make USB essentially completely displace FireWire? With 90+% of all computers unable to use it, to whom were FW3200 device manufacturers going to sell their products?
