Sandy Bridge, or wait for Ivy with on-chip USB 3.0 support?

So I was reading an article about the leaked Intel processor roadmap, and I read that Ivy Bridge will be supporting USB 3.0. That said, everywhere I look, I see motherboards with USB 3.0 on them. Does this just mean that Intel will be shifting the USB 3.0 controller directly onto the chip? I'm sure that this probably has some bandwidth advantages, but is it really worth waiting for?
 
No, it's not worth waiting for IMHO. Internally, the USB 3.0 implementation will probably still use PCIe (just with no physical ports).
 
What do you mean? USB 3.0 ports are already found on most major motherboards. I don't understand the difference.

I thought it would be for a throughput advantage, but really, using PCIe lanes...who cares?
 
It means Intel will include the USB controller in one one of their chips, most likely the south bridge (I don't feel like actually looking for this info, right now 🙂). Currently, a 3rd-party controller chip is used.

Aside from lower cost (one less chip on the board), and more ports being USB 3.0, there won't be any real difference.
