Sony recently revealed the 40GB PS3 system that will release at a lower price in the UK and Europe. This new system will lack backwards compatibility with PS2 games and have less USB ports. However, another difference appears to have surfaced.
According to PSNow!, a Sony representative has stated that the system will have a matte finish, instead of the glossy black that covers every PS3 model thus far. Moreso, however, is that this new SKU will supposedly be silver, giving it a noticeable aesthetic difference.
This has yet to be confirmed, so be sure to check back for more details.
