Originally posted by MarkJerling While it seems strange that they've not gone to USB 3 the difference in transfer speed may not really be all that different. There are very few USB 3 devices that read faster than 100Mbps and USB 2 tops out at 60Mbps. The theoretical maximum speed of USB 3 is 640Mbps. And, that's not even considering write speed which is much slower, typically lower than 40Mbps. What this means is that the perceived advantage of USB 3 over USB 2 may be just that - perceived.
The camera has an Ethernet port for transfer. Sony cameras have the ability to charge the battery in camera. Just plug it into the USB port. Photographers who many shoot professional sports are wired and photo's are streaming to editors in real time who then post them.

It's worth taking a moment to admire the hardcore Olympic photographers who wake up long before sunrise in some cases to ski out to their locations. The standard kit for a Getty photographer includes four camera bodies each outfitted with different lenses: 16-35mm f/2.8, 24-70mm f/2.8, 70-200mm f/2.8mm lens, f/300mm F2.8 lens. As you can see in the image below, Getty photogs travel with a mixture of Canon and Nikon cameras bodies, while the AP is an entirely Canon shop. Without fail, these photographers are using either Canon 1Ds or Nikon D4s. Unlike most disciplines where you could get away with something other than flagship DSLRs, sports photography requires the 10-15 fps speed that you get at the top of the line. That's a lot of gear.
The second a photographer fires the shutter on a camera, the resulting image— a high quality JPEG, not an uncompressed RAW file—is transported by ethernet to Getty's central editing office in about 1.5 seconds. There, a team of three editors processes the photo. The first selects the best image and crops it for composition; the second editor color corrects; and the third adds metadata. The whole editing process is done in 30-40 seconds. Once the last editor is done, the image is blasted to the world. It takes about 90 seconds for the images to travel over redundant 100 Mbit/s dedicated lines to Getty's data servers in the United States."
