Ps4 – Does the Playstation 4 Camera work on the PS3

This is a known issue for the PS3. Bethesda is working on a patch, and it's slated to be released after Thanksgiving.

Update: Looks like there'll be a patch in a few weeks for this issue.

Yes and no; the had drive type is the same, the hard drive will physically work in the new device. However, PS3 hard drives are encrypted, so if you just move the drive into a new PS3 the drive won't actually work; you'll have to reformat it.

Instead use the Data Transfer Utility to transer as much as possible to the new PS3, though some things don't move over; notably PS1/PS2 saves, you'll have to manually copy those to external media. If you can get the old PS3 to work by any means, do this instead if you want to keep that data. Do NOT reformat the drive until you have the data you need (or you think you'll never get it again.)

I am not sure if you have your old PS3 fixed if it will still read the same data; you'll want to ask Sony Support because it depends on the type of repair; if the device is irrecoverable, you can't get the encrypted data back.
