There was a Sony interview the other day comparing the bandwidth of PS4 to one similar to what Wii U uses.
The way the Wii U works can lead to some really fast data transfer rates but only if developers are willing to put in the time to make software for that type of memory.
What this could be is Nintendo giving out just such software to help developers. It's also been reported since launch that several game engines, middleware, game development tools, whatever else I am missing are Wii U compatible.
Also my understanding is that Nintendo has always provided tools to developers if they want them or need them.
