I think PS+ is profitable. It gives us older games for free, which is tempting us to buy the DLCs. I bought DLCs to some games that I wouldn't buy in the first place, let alone the DLCs to these games, so the developers got money they wouldn't be getting otherwise.
Also getting the pricecuts made me buy a couple of PSN games I probably wouldn't be buying for the normal price. If anything, it makes me not buy used games, cause I'm getting them from PS+ for free. I don't think PS+ is competing with new games.
For Vita - Uncharted is a great magnet, Gravity Rush didn't sell anyway (unfortunately), so isn't much of a sacrifice. Remember that to get these games you have to buy a big memory card and suddenly PS+ on Vita becomes profitable.
All in all I think it's a briliant thing. It gives some money to Sony, makes used games less attractive, encourages us to buy DLCs and PSN games we wouldn't be buying otherwise. There is no doubt in my mind that it is profitable for both Sony and 3rd parties.
Wii U is a GCN 2 - I called it months before the release!
