The free game a month isn't like PS Plus, because you get four games on that programme, or if you just have a PS4, two games. Hopefully she is correct though regarding keeping them as long as you have a subscription, but that is against what has been said elsewhere.
Similarly hope she is correct about the price drops. Price is the biggest issue I have right now, especially for accessories. The Pro controller is not impressive enough to warrant being $70, for example.
