Owning both consoles this early is kind of madness i'm afraid, you will possibly regret it.
At least wait for the exclusives to come out, you are more likely to be able to grab a nice bundle or something. It doesn't hurt to wait and see how the games pan out review wise either.
If you are just one of those people that needs new gadgets, buy like a vita or something.
I mean unless you are going to miss multiplayer with friends or something, don't feel like you are missing out on anything - there is nothing out for these consoles at this point.
