I expect that PS4 will have trophies for all new games as standard it was only initial PS3 games that didnt have them, it was added as PS3 feature after launch. So I would assume its for PS3 games.



MGS4 trophies incoming ?(I wish)



However it seems there are issues with this alternative approach. e.g for a digital download you can not rely on a prior analysis of the hard disk access because the game binaries will stored in different places on the hard disk for each user ... and also even for bluray games the games are subsequently patched with patches stored on the hard drive - meaning a given bluray disk location may not even be accessed after patching ?. So this seems like a lot of work for someone to maintain when you could just patch the game!



I am all for trophies though, I like them mainly for a permanent memory of progress of games long finished.
