Should I trade-in 3DS for Wii U or keep 3DS?

The obvious answer is to keep your 3DS.

It has better games than the WiiU.

shame on you for even thinking of trading it in. >:(

I coin flipped on the Wii U, got scrapped, I coin flipped on the 3DS, it's only slightly better. I am now torn between which will actually have the games.

Look at it this way.

If you don't see anything you want to play on the 3DS NOW then you're never going to find anything to play on it or a WiiU. Just trade in your crap and get a Sony or a Microsoft or heck a Tablet if you want.

Why not have both?

keep the 3DS, the trade in credit is worth the same as renting your mouth out for 10 minutes to some guy on Craigslist

Keep the 3DS, its the second best system right now next to the PC. I'm sure you can find something to play because of the massive 3DS + DS library that has something for everyone. Seriously, don't limit yourself to stuff that just recently released. The Wii U, as of right now, is incredibly weak in a lot of genres and needs time to grow beyond the few genres its strong in and the Wii lineup that is basically carrying it. I would check back next year because I have a feeling Project X and SMT X FE is going to really do some things for the state of that console.

It's not anybodys decision but your own you have to think before making such a big choice.

well.. do you plan on playing Zelda a link between worlds or Mario party island tour? Personally, I would hate to miss out on Mario 3d world and donkey kong.. Especially Donkey kong.
