No 3D glasses are part of the 3D HDTV that must be used for a PS4 to show something in 3D
The PS3 will play 3D movies on a 3D HDTV ot the new 3D display for PS3. There is no PS4 It will also play 3D games. You only need to buy the 3D games and a 3D HDTV and get the latest PS3 updates and any of the PS3s will play 3D. Without a 3D HDTV you can not get a 3D picture
Yes it will just like the PS3. There is no PS4 until it is released forecast for December 31 2013, but without a HDTV with 3D capability to view in 3D you can not have a 3D picture. Everything will always need 3D HDTV or monitor to get 3D. The PS3 has 3D already if it has the latest updates, but just as you can not have a 1080P HDTV picture on a 480i standard TV you need a 3D TV to get a 3D picture. Most new top HDTV models from all the major brands are only available with a 3D capability even though you need not watch anything in 3D on them and can still watch everything including 3D programming in 2D. Just like a couple of years ago you needed to have 1080P if you purchased the top models the brands offered. Sony's newest top model is not only 3D but something they call 4K Ultra HDTV and said to offer 4 times the detail found on 1080p Full HD
The PS4 has not been announced, is not sold, has not been seen at electronics shows at the time of this May 2010 postings. Since the PS3 was in 1080 P HD and is now updated to also play 3D it is likely the PS4 will have further technological advances.
PS3 is releasing the PS3 Move without changing the Name to PS4 and the already released the PS3 with 3D capability without changing the name to PS4. They will continue to release improvements to the PS3 without changing the name as long as the older models can continue to have the new features through software updates.
They do not make a PS4 and may never name a console the PS4
