You can not deny this mans wisdom.

I wouldn't sell any of them unless you really need the money or the space, or plan on buying a newer revision of them. It's nice to have them just in case.

well it depends on what games you want to play in the future that are coming for them. If i had them both i would keep them both as 360  will get Halo 4 and PS3 will get the last guardian but that's juts me. but who knows when the last guardians comes out I would tell myself and sell the PS3!

you lose on selling either of them though

i'll give you 50 bucks for your PS3 and all the games! that's a great deal man take it!

sell them both and get the WiiU gratis.

Neo Geo

You can get a lot for that.

I never trade in my consoles. I have every system I've ever bought going back to Atari plus more I've picked up years or decades after their release.

I would never trade in my current system, that I still enjoy when I could just set some money aside for a new system down the line. With games like Halo 4 and The Last Guardian it's clear that the PS3 and 360 still have life left. I personally am not interested in any of the launch window Wii U games so trading in the system with games I am looking forward to would be a huge mistake.

If I did trade in a system for a newer console, I'd eventually feel the need to replace it. I still play my Dreamcast, SNES, Atari 2600, etc. There's no reason to believe ten years from I won't be playing Halo 4.

How much do you get by selling each respective system? Maybe that helps your decision?

Don't get the WiiU at launch, save a little longer, buy less games. Now you get all three.

sell the xbox

It boils down to Halo 4 vs. BluRay + free online. I would sell the Xbox but I wouldn't have bought one in the first place.
