yes its very true, Intel is the company fronting this, The already have the cards and cables. 1GBPS eathernet is already hear, 10GBPS Eathernet is on its way, with in 6months, SATA 2 is on its way, with in 3 months USB3 will start making its way through in about 2-4 months, The speed is there only 1 thing has to be done and thats running new cables. So beleve it.
Its already started with verizon FIOS. Fiber tops out at 800MBPS so far with a distance of about 20,000 FT. The biggest problem is your HD can only right at 150MBPS when SATA2 starts being used then its 300MBPS.
