My recommendation is Playstation. If you choose to go last gen, one point you missed is free online. Also, blu-ray player. Much better and wider selection of games.
It will have support for longer, especially if you like Japanese games.
For you, as a Nintendo owner, I would recommend going with PS3 first, enjoy its vast library of games, both exclusive and 3rd party, and then, once you've had all the fun, in a year or so, trade it in for an upgrade to PS4 which will have a nice sized library by then.
