While charging for online wouldn't be a lot of money (say 4 million users times $50 only equals a fraction of Sony's current losses and that's a very rosy outlook for the servide) Sony is going to need money coming in from somewhere. It sure isn't coming from traditional hardware and software sales while the expected bluray bonanza is still years in the future. Sony will have to weigh that against the reality that most gamers see Sony's free internet as one of its biggest assets.
I wouldn't be surprised if Sony eventually charges but it would have to be after deep price cuts and a massive increase in online content starts driving sales. Otherwise Sony would probably kill more sales and market share than the increase in profit, well drop in losses, is worth.
