I bought the LA Noire one. Only cost 800 points instead of 1600, which is a nice saving.
Like Raban I think it's a great idea that would work for some games (Fallout, Halo) but not others (LOLEASPORTS) and it's all down to the execution.
The problem with this one is that the price is out without any indication of the content, you don't get all the content ("the first four"), and the up front discount isn't that enticing. Plus it's likely to be multiplayer content which cuts your audience down as well.
The funny thing is this is really just drip feeding an expansion pack under a different name and you're paying up front. 10 years ago we had to wait 8-12+ months for an extra $30 of content.
