Looks like starting April 2 the new price for a Station Access pass will be $29.99/month.
SOE supported their decision by stating:
"We know that rate adjustments are never popular, but the increase is driven by our desire to provide our Station Access subscribers with a consistently high quality entertainment experience, as evidenced by our most recent addition to the Station Access subscription plan, Vanguard: Saga of Heroes."
Could this rate increase possibly imply a monthly fee might soon be applicable to Ps3's online experience? Although the effect this news will have on the price status of PS3's online experience is yet to be known, hopefully, news concerning the Playstation Home Network will clarify the matter.
