Last week's 3.30 firmware update for the PS3 did more then just add 3D capabilities to the console and several Trophy enhancements to the console, it also added future support for Remote Play on PCs - namely Sony's VAIO brand.
The official VAIO site doesn't list much information on the VAIO support other than simply stating that it allows the PC to connect to the PS3. This move ties into Sony's recent effort to tie PSN into all of their products.
The trophy enhancements come in the form of new sorting options, and hidden trophies now display exactly that wording, as opposed to ???.
