3D? As in three dimensional images? Or "Creation, Distribution, and Display"?
In anycase, I'm not convinced that Sony has got it. For photography, they assume blu-ray disks to slide projectors is the family model. How many people here still go to their friend's house to see slide shows of their friends' holidays? As for us, we mostly use Flickr and internet forums. In that sense, both distribution and display has so far been relatively untouched by Sony. If they're entering cloud computing, they're entering it quite late. Google, MS, Apple, Ubuntu, and a few others are already there. And Google is providing basic off-site (cloud) storage for free.
To me, Sony's strengths so far has not been in software development, and even if they did contract another company to provide their cloud computing, I don't think Sony has the managerial experience to know how to get the most out of it, yet, either. However, Sony in Japan has had a music sales service, similar to iTunes and Amazon music, but that has been a failure. My guess that their music service was a failure for two reasons, one being how it was tied in with their music players, and the other in artist distribution agreements; they didn't have all of the big names available, where as iTunes had the most. Having said that, I'd dare say that they are perhaps smart enough to get in and give it a go before Canon and Nikon, anyway.
It'll be interesting to see what happens, anyway.
