No matter what, the BD drive will be the slowest part, the weakest link. They need to lean on hard drives more.
Ultimately I don't think BD drive speed is going to be a huge issue. With the PS3, at launch, there was a 20GB HDD model - less than the size of a single BD. They could rely on temporary caches and partial installs, but full installs could never be mandatory, and every game had to design around this. (Not to mention cross platform games had to conform to the 360 which could be HDD-less...ugh.). The BD drive had to be relied upon to stream directly from it, in order to maintain compatibility with the older models.
With the PS4, even the minimum realistic drive size of 250GB is bigger than the biggest BD. They can absolutely rely upon having the space for a full install for all games, and design accordingly. Given that all games are going to be available digital, every game needs to have a fully installed option/version anyway.
Given all that, the simplest thing is to just design one version of the game - a fully installed one, that's playable with a partial install. The disc needs to be nothing more than a local cache of the exact same thing you'd download from the PS store, only much faster (6x BD drive is roughly equivalent to a 300mbit Internet connection).
The BD drive then ceases to be the weak link it would be even at 20x. A HDD is still 10x faster at random access, it'd be crazy to constrain their design to accommodate slow BD speeds, when they've got a huge and much faster HDD in every box. Faster BD drives in later models could then provide a faster install, but getting a game to a playable state shouldn't take more than a few minutes even at 6x, since they'll need to keep the minimum playable state pretty tight to accommodate much slower Internet downloads. Once it shifts to the background install, BD speed is basically irrelevant.
It'll be a nice feature to tout for the PS4 slim in 2016 - 20x drive, SSD - super fast full installs and loads, but full compatibility.Edited by bd2003 - 3/21/13 at 9:40am
