Today, Wikileaks published a database of all of the data leaked from Sony Pictures in last year's hack, comprising 173,132 emails and 30,287 separate documents. If you go here you can search the database: https://wikileaks.org/sony/press/ Search for something like "Xbox" in the database and you can get an insight on how Sony was thinking in regards to the competition. I found it pretty interesting Sony have a timeline of various console hacks, presumably showing how long it took for a proper PS3 hack: https://wikileaks.org/sony/docs/05/docs/Hacks/PS3 timeline 7.txt Also Sony comparing their digital content delivery to Microsoft / Samsung: https://wikileaks.org/sony/docs/05/docs/DECE/Sony and DECE v4.txt It's a pretty interesting insight in to how things work at Sony.
