Now that the OP has discovered that you DON'T have to download a patch before you play, this thread seems to have broken down into a collection of misinformation about the PS4.
First, downloading on the PS4 will be faster. That's because of the way the PS3 receives data, it's convoluted and slower than it should be. Sony has confirmed that this process has been improved significantly. The issue was, really, that Sony did not expect digital distribution to be a Big Thing and did not optimize the PS3 for it. That is also related to the unnecessary way the PS3 has to store the content before it can be installed. That, obviously, has been changed. No more installations, we've known that for a long time. Data will be installed on the fly as it streams.
The same goes for installations from the disc, that's also gone. Anything that needs to be installed to the HDD will be streamed as you play so that there will be no initial waiting. The best developers had mostly already solved this on the PS3, to be honest.
HD resolution and the rise of digital distribution brought a lot of growing pains to the industry. Most of those will be fixed next gen.
