Development time on the Wii is already fairly quick, due to its architectural similarities to the Gamecube and general lack of difficult-to-corral horsepower hidden within magic-seal cores (you have to unlock them with the level 7 key). Takeshi Shimada, a Nintendo employee who works on toll packages for developers, spoke about some of the upcoming projects he had in mind.
In addition to updated handwriting and speech recognition software for the DS, Shimada is working on a host of tools for the Wii. First off is a Wii emulating technology for high-end PCs to mitigate the slow "loading time" of putting recent code and assets onto a Wii unit itself (if this ever gets leaked ... ). He's working on some "fur-shaders" (which might apply also to grass or carpet textures) and other graphical tools, and finally, an advanced text-to-speech system that seems to be all the rage these days.
What does this mean to you? Hopefully, prettier fur. We salute you, Shimada-san!
