"The most common charge leveled at the Xbox 360 by Playstation 3 devotees is that Microsoft dares to charge for its Xbox Live service, unlike the free PSN. Not for long!
Now the question is what exactly will they be charging for. Will they charge for online multiplayer, like Xbox Live? Or will they offer up some new premium goodies to entice people to pay up while leaving the current offerings up for free? In any case, it looks like there's soon to be a little less ammo in the console wars. But don't worry, Sony fanboys: you still have Blu-ray. No one can take that away from you." source
