No no no.
Ive done a lot research on this subject, here is what they ARE going to do. I wish i could give you the link, but i forgot where i read it.
What you have right now will ALWAYS be free, but if you desire more such as voice communication while you're in one game and your friend is in another game, you will have to pay $3-5 a month.
So if you want more than you already have you will have to pay a small fee, but if you are happy with what is already given it will be completely free. There is absolutely nothing wrong with this, if you are happy with what you have, great (like me). But if you want more you will have to pay.
If anything, this is a good thing.
Thank you, I was going to say the same thing because I researched it as well, and I knew is
people heard "charge for psn" then they would freak out...
