USB is not that big of a deal. I've been using a USB external drive and it is still slow as a dog. USB 3 is NOT eSATA. The bus resets too so it isn't something you can use as an enterprise port. It is basically useful for thumb drives, microcards, and the external drives you use for temporary storage. Lightpeak has a million more applications. Intel championed both interfaces as well as just about every other interface on your computer (PCI, SATA, etc.). I think Lightpeak is just another way to get some serious money from licensing fees before opening it up. Did Intel slowplay USB3 adoption for Lightpeak? Maybe... since Lightpeak can be used for the same uses, but lightpeak's bandwidth forces you to use PCI lanes. Until they change the core logic and come up with ways to improve overall system bus speed while still cutting power, you're not going to see a lot of lightpeak and maybe Intel finally realized that and bit the bullet on supporting USB3. Lightpeak may very well take over for USB3 in a few years when the motherboard logic fully supports it.
