Well there is a small possibility that sales might increase if Sony started charging for PSN. Many people falsely assume that Xbox live is a huge leap over PSN just because Microsoft charges $60 for it. They think that just because they are paying for it, xbox live just has to better. In reality though PSN and Xbox live are very similar give or take a few feature like party chat which isnt added just because PS3 hardware can't handle it. If Sony starts charging for PSN and does revamp the service a little, then sales might actually increase.
/my 2 cents
