USB/SATA 3, Did Intel Blow It?

Did Intel not see SATA & USB 3 coming when it designed the P55 chip(set) with its 16-lane on-chip PCI-E controller? Or was Intel already too heavily invested in the P55 design and left with no alternative other than foot-dragging in the hopes that it could get market saturation before anyone really noticed?

USB 3.0 was delayed for unknown reasons in chipset integration but is put out by mobo vendors as PCI/PCIe x1 expansion cards.

SATA3 at this point is still useless since not even a Intel SSD can fully saturate a SATA 2 link.

But I have heard that a lot of companies are testing their SSDs with SATA 3 and are getting pretty good speed increases, some well over 300Mb/s per drive. But you have to remember that SATA 3 is a industry standard and has to be given when its ready to be used. You don't see mobos with DDR3 before you can buy DDR3.

By limiting the on-board PCI-E controller to 16 lanes, the P-55 already limited graphics choices to a single 16x config or dual 8x. My point being that if SATA/USB 3 were already on the drawing board when Intel was mapping out P-55, wouldn't someone have noticed that 16 lanes were going to be inadequate if trying to take advantage of all three; dual gpu (whether on one card or two), SATA-3 and USB-3? Look at the workarounds both ASUS and Gigabyte have had to resort to in implementing them on their P-55 mobos. Note that I am appreciative of both Intel's and AMD's cpu innovation, so I'm not trying to instigate brand warfare here; this just seems a major oversight on Intel's part and makes their foot-dragging on USB-3 development a little suspect, at least in my view.
