You cannot play Playstation 4 games on a Playstation 4 console. You are also unable to play Playstation 3 games on the Playstation 4.

No, the Playstation 4 is not backwards compatible and you can only play Playstation 4 games on it.
the playstation, the playstation 2 and the playstation 3 (that'd be 3 versions.) both the playstation and playstation 2 had slim versions released of them and the playstation 2 had a special siver or pink edition in an attempt to attract new female gamers.

It was said at a playstation convention on TV that they were planning on making a playstation 4. They are not quite sure when it will be out.
No it will not
As of this writing, Uncharted 4 will be only for PlayStation 4.
It is not a new PlayStation just an option system to be added to the PS3 called PlayStation Move
