Last I checked for US it's still 50 for full game. It's 20 lbs in UK for full game right now, but keep in mind, that's not 20 dollars...
Anyways, for those saying just buy it or worse, "You weren't interested anyways." You miss the point. They promised us something and they haven't given us something. It doesn't matter if it is "just a demo" or if we planned on buying the full version, they haven't lived up to their word and yes, people should hold them to their word. And not just reward them for not buy buying the game instead. Oh, and just so you know, just cause some one has patience to wait for a game doesn't mean they had no interest. Just cause you have no willpower doesn't mean others don't. Or it could mean that we are interested enough to try it out and see if we want it but not interested enough to risk the money (for some of us even 30 dollars is expensive so I'm picky what games I get with my money. And honestly, without Lamborghinis they will really have to wow me to get the game. But I'm willing to try it to see if they do wow me. I'm not willing to risk even 30 dollars though on whether it will or not).
Granted, I will give the people who are proposing that maybe they still don't think that the servers are ready for the PS+ version and this isn't some malicious way of not giving us what we promised (though I will admit at this point I wonder even if it wasn't malicious if they'll just think no one is interested anymore anyways and not give it to us). But I do think it's not unreasonable to ask that they give us a little something more than they were in apology for the fact that they messed up (on purpose or not, they still messed up. And why are the customers being yelled at for being upset at that?). Like a much better discount on the game than what you can get full price (not just 10 dollars off). Or if possible (I realize this may not be easy to change what they are offering), a little more in the demo than they were going to offer us. But I realize that one might not be feasable (I don't know much about programming and how hard it is to change what the demo gives us).
Just something as an apology for the wait would go a long way in good customer service and show us that they truly are sorry.
