Some games take up over 40 GB and we don't get the full 500 GB to start with. The size of the hard drive was a non-issue for me with the PS3 but with the mandatory game installs to the HDD I can see how this can add up. I don't think I have a lot of games but with demos and what I do have I have used up almost 350 GB already on my hard drive. I can easily delete some of the games I don't play and just add them back later if I want but some people may be limited on their bandwidth too. I can definitely see upgrading the PS4 HDD as being far more valuable than the PS3.
