Everything I've seen relating to game streaming so far has been a shitshow. Crackdown 3 was supposed to use some cloud computing thing to calculate the physics of giant crumbling buildings, but that game just ended up delayed and quietly launched to bad reviews. Crowbcat even put up a video showing how a lot of things in that game look worse than the first one from 2007.
Yeah, it's likely just PR crap, blah blah blah, this shit's gay.
This is more or less about making a stable network for data streaming and online infrastructure. Epic would also have a stake in this too since they accepted seed money from Sony to make the epic store.
Essentially this is about how everything online works under the hood and how to make it better. There's a ton of potential stuff like having the option for a lower bandwidth download for less than optimal connections or if you're at a data cap. Basically a corporate mandated Fitgirl repack but without the bitcoin miner.
