USB 3.0 demonstrations dazzle: uncompressed 1080p transfer proves simple

You've been adequately teased with what all USB 3.0 (or SuperSpeed USB, as we tend to refer to it) can do, but a gaggle of companies took the chance in San Jose, California to really demonstrate just how quick the protocol is. Most notable was the demo by Synopsys, which prototyped an HDTV video transmission system based on USB 3.0 and showed to wide-mouthed onlookers that an uncompressed 1080p feed at 30 frames-per-second could be whisked along at around 450Mbps. Sure, USB 3.0 has wireless HD to watch out for, but given that said technology is currently on track for an August 2298 release, it could really do some tethered damage in the meanwhile.

I can stream 30mbps 1080p videos over my 10/100 LAN. Other than for future proof, what do I need this for?

August 2298. Ain't that a ways away?

I'm not sure what this could mean. Will HDMI be made obsolete as soon as this is brought to market?

HDMI still has more than double the bandwidth of USB 3.0 and i'm sure they're working on even faster HDMI. This probably means the end of the line for firewire though.

Except uncompressed HD is 1.5Gbps...

Yawn. FireWire 800 has been doing 800 Mbit/sec for years.

Highly Ranked

USB 3.0 max data rate is near 5Gbps, some demos are showing 3Gbps actual.
Note 1080p at 30fps is 1920x1080x24x30 = 1.5Gbps, should be able to handle 60fps.
HDMI is extended to handle greater refresh rates or color depth (if ever used for HD video).
DisplayPort is capable of scaling to much higher resolution, color, and refresh.

450Mbps? I'm reading it like megabits here, not megabytes. If that's the case, then it's really not that impressive, since USB 2.0's standard has a theoretical maximum of 480Mbps.
