I doubt it'll go anywhere either. Like Brightside says, if it did, it would open the floodgates, not necessarily a good thing for anyone.
That Sony statement is shocking. I'd put more of the blame at their door. They talk about him being an indie developer and not having a PR team - whose fault is that? They could have stepped in at any point, as to even the most casual observer, Sean Murray was out of his depth. But no, they were happy to coin it in initially, then distance themselves. If there is to be punishments, they need to be levelled at Sony most of all.
