But Develop’s source, speaking on the condition of anonymity, explained that multi-tablet support is one of three remaining variables for the next-gen console. The other two are RAM capacity and processor speed.
The person said Nintendo appears to be on the cusp of solving the technical conundrum of a single Wii U device supporting two tablet controllers. The source added that there was no indication, and very little chance, that four tablet controllers would ever be supported.
