Then there's all the folks who brought SOCOM, Portal 2 and other multiplayer-heavy titles that have no where to go and no one shoot. Reviewers who get their code through download codes will also be missing out (was hoping to do Persona 3 this week, but that looks unlikely).
All of which means Sony will have a real struggle on its hands to repair the image of PSN, as well as make the service bulletproof in future. The very latest from Sony is a decidedly unhelpful:
"There are a number of sources speculating on the nature of the PSN issue and ETA's but there has been no official feedback on this as yet"
