If you've got a PS3 and are planning on buying Call of Duty: Ghosts tomorrow, drop everything, you can start right now.
Sony has announced that the PSN will have pre-loads of the game available now to download and install on PS3 machines. That means that at 00:01 tomorrow morning, Tuesday 5 November, you'll be able to start playing immediately.
If you were on the fence about buying this title because you wanted to wait for the PS4 version, don't wait. You'll be able to upgrade to a PS4 version of the game for a tenner extra when it arrives with the console's release on 29 November. That includes carrying over all your multiplayer progress too, in case you were worried.
Here's hoping this version isn't flakey like the GTA V release which had a few corrupt files upon completion of its arduous download, a huge 18GB file.
