This is both good and bad - see below.

I understood it to be two lanes ("tubes"? :-)) in each direction.

I'm not sure it will gain much here, except if it already universal in 
peripherals or the video angle takes off. Most devices would be pushing to 
sustain USB3 speed, let alone 10Gbps. USB will be hard to displace for most

They have it working over copper, so I'm not sure optical will take hold, 
except in niche markets.

Probably not, because of the security risks. Remember that its PCI-E, so it 
can (probably) reach into memory (like Firewire). That means that anyone else 
on the "network" can search through memory (extracting loaded files, keys, etc) 
and perhaps modify running code.
