Was going back to re-download The Last of Us after getting a real itch for a second play through lately and remembered that the digital version of the game came as a ~150mb installer that unpacked into the 27GB game itself. I haven't seen any definitive confirmation from anyone or anywhere that says whether this is now the PSN standard for digital purchases or if most games still operate on the 10GB installer + 10GB game model that made for some really frustrating situations where having 40GB free just isn't enough to download two games that easily fit into that crunch (in this case, Last of Us and Bioshock Infinite, which I wanted a third play through of now that I have speakers running out of the PS3 rather than just my TV).
I will say that download speeds are officially awesome now, basically the same speed I get from torrents. I think when I first bought Infinite back in the spring it took 3-4 hours to download and another 45 minutes to install, but this time it's only estimating 80 minutes for the game to finish. Thank you PS4 for making the PS3 a better experience!
