PS Plus looks like a load of ***** then really. Site says 50 Dollars a year so im guessing UK would be 40ish. Looks like its old classic games and things like that you get free. The odd early demo or beta and some themes...
"Each month there will be 2 dynamic themes, 2 premium avatars and premium game elements/add-ons for you to download and many of these will be exclusive to members only. These are yours to keep forever once you have downloaded them.
Plus members will also be given exclusive PlayStation Store discounts each month that are above and beyond the current Store discounts available to everyone. These discounts will range from 20% – 50% and anything you buy with these is yours to keep and enjoy forever.
Finally, wherever possible we’ll be making sure that members are included in some selected demos and beta trials early, before they go live to everyone, so you can be the one to tell all your mates about the next big game they ‘must’ get"
