I personally do not think PS3 is doomed. As you mentioned, there are a lot of games coming this year and the years to come. Certainly, some have lost their trust with Sony and will decide to invest more time and money in another console. However, some will still continue buying Sony products and what not.
And yahh, Sony will lose money from PSN being down and also from lawsuits and trying to fix the problem. Its good to note that every computer system out there are prone to being hacked. I have been reading the news and looking at alot of blogs, and it is known for companies to not reveal such an intrusion to not recieve unwanted press. Sony did what they thought was the best course of action.
Lets just hope everything will be up and running in not time, and that it will not happen again.
Remember, no security sysem is invincible. Even with updated security measures, it might happen again to Sony.
