Nintendo has teased unannounced projects that will feature communication between 3DS and Wii U. The company has revealed that it has been experimenting on wireless interface between these two consoles.

Nintendo had revealed that during the E3 that players will be able to transfer character data between Smash Bros. Wii U and Smash Bros. 3DS consoles. Also, Mii characters can be copied from one to another.

"With Smash Bros., because the two games have the same gameplay and the same controls, that game in particular is designed where you'll want to start playing on the 3DS first and build up your characters there, and then transfer that character data over to the Wii U and play with them there," Shinya Takahashi, general manager of Nintendo Software Planning and Development said in an interview with IGN.

Though the company has been thinking over these features and there is no credible reason why it has not been implemented, one of the reasons he offered was that these features do not fit into the present set of gaming titles. He added that the company created the Fit meter with Wii Fit U that can connect Wii U GamePad wirelessly and transfer the data. Though there were plans to have similar functionality with 3DS, it was not implemented.

"It was a kind of interesting concept based around that, but we ended up not doing anything with that idea. It hasn't really worked its way into the titles we've been developing," he added.

"But there are some things that we're working on that we haven't announced here at E3 that do involve some sort of communication between the Wii U and 3DS," he revealed.

Further, Takahashi revealed that these features are likely to make way into popular games like Mario and Donkey Kong. "We are thinking about that with Mario and Donkey Kong," he said.

This was all the information that was revealed rising questions if Nintendo plans to make separate Mario and Donkey Kong games with the mentioned features or it will have game that will be having both the characters. CVG suggests a possibility of a puzzle series Mario vs. Donkey Kong.
