If you don't have a console yet it might be better to wait the 6 months for the PS4 since you will have to spend much more than just the $399 cost for the console or the $499 for some of the bundles.
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.
You still have 6 months to wait and it's june 2013
Wait for the ps4 it will have better graphics
The PS4 or the Xbox720 is not likely to come out anytime soon. If you want a PS3, go ahead and get one.
You can get a PS3 and the PS4 is not an actual product. If you want a console buy a PS3 because the PS4 can not even be preordered it's release is so far in the future
PS4, it's a very good console.
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.
Because PS3 and PS4 are different consoles. If you have Minecraft PS3 and try inserting it to a PS4, it won't be able to load because it changes the features in the disc. You might need to sell your Minecraft for PS3 and use the money to buy it for PS4.
No, the PS4 does not have backward capability and cannot activate (play) PS3 or PS2 games.
They will have PSN like the ps3
No they have a different plug in to charge therefor the ps3 controller won't connect to the ps4
