Yes, just like the Xbox 360 has been doing since the launch of Netflix on that platform, the PS3 will be receiving a dedicated app. Users will need only to connect their PS3 online account with their Netflix account and can begin streaming content on their game system immediately.
Currently, PS3 users must wait for Netflix to mail them a special streaming disc, which contains the app. The disc must be in the PS3 at all times when users want to watch streaming Netflix content.
The only rub with the Xbox 360 is users are required to sign up for the premium Xbox Live Gold service to be able to access the Netflix app. So far no such restriction has been announced for the PS3 app.
Sony confirmed today that the app will be coming out this month, as originally promised back in the summer.
The Wii will remain the only console that requires a special streaming disc to access Netflix content. Because of its limited hard drive and inferior system infrastructure it is highly unlikely Nintendo's system will ever see a similar transition to a digital app substitute.
