Sony has announced that an optional firmware update for PlayStation 3 will be released next week.
Version 3.15 is set to introduce a data transfer feature for people who've bought a new console, along with the chance to play PSP minis on PS3.
The latter has been rumoured for a while, and will be a reality from 17th December, with Sony aiming to get "the majority of the current minis" ready in time. From then on, PSP minis will work on PS3 and PSP.
The data transfer feature, meanwhile, is designed to allow PS3 upgraders to copy things like save data across easily rather than mucking about with backups. It can't be used to salvage copy-protected saves though, sadly.
Full instructions and slightly more info can be found on the European PlayStation Blog.
