The lights are on
I am in the process of possibly trading my old Wii System towards either the Wii U or the 3DS. Looking at the Wii U console; reading about it's capabilities, game titles and future releases, it looks like a safe bet. Yet, I do enjoy the simplicity of the 3DS. I do enjoy the virtual console to recall those old games and both of these engines have that. What would your suggestion be?
Keep your Wii, buy a Wii U.
After you have the Wii U home, transfer all your Wii stuff to it.
Then you can safely trade in the Wii towards Wii U game.
