I really don't get why people want to burn Sony to the ground but nearly no one is talking about looking for the hackers who did this. You know, if someone can somehow capture the hackers, then this whole nightmare will simmer down a bit. The hackers are the ones to blame the most, not Sony. I mean Sony is still to blame for their poor security, but it's still the hackers who hacked it in the first place. Maybe if they ever do find the douches who did this, they're the ones people would sue.
And no, I doubt that they're not going to release the NGP. They've already started development, it's going to cost them even more to let it go.
And even if their gaming sector falls, Sony is a very powerful electronics company first and foremost, and thus the company as a whole will not be destroyed or anything. Before the PS1, Sony was still fucking damn rich. The probable reason why they decided to enter the market is because it was new and a very good investment, with the fall of Sega and all.
