No, players on PS4 cannot play with those on PS3 in Neverwinter. The game does not support cross-generation play between these two console systems. Each version operates on its own separate servers, which means players can only interact with others on the same platform.
can you play destiny on the ps3 and play with a friend that has destiny for the ps4
No you will not be able to play the games either way. Systems changes on the PS4 allow them more design capability for games and many titles will be released in a downgraded PS3 version. You still will have to have a PS4 to play PS4 games and a PS3 to play PS3 games.
No, the PS4 does not have backward capability and cannot activate (play) PS3 or PS2 games.
No it will not
No, the PS4 will only run the games made for the system. But there is a application on PS4 called PlayStation Now which will allow you to play PS3/PS2 games for a price.
Keep the PS3 and play with your friends and wait for them to get it, or you can just buy a PS4 and wait for them to get one.
In short, no. Sony haven't released any information regarding a PS4 yet, so we can only assume that you cannot. It is highly likely you will be able to play PS3 games on it, that is - if it really comes out.
No
No, if ps3 could play online with ps4 users evryone would just buy the cheaper ps3. That would cause sony to lose money which they do not want at all.
The PS3 will not be able to play the PS4. They both are on the Playstation Network (PSN) and Playstation Plus will work for both of them as it does for the PS Vita and PS3
No the PS4 when it comes out will not play PS2 or PS3 games because it has proven to be a unlimited expense filled with great difficulties and problems if not an impossible task
yes!
