Shimada revealed that Wii might soon be able to read the news and weather headlines to you, with a new text-to-speech tool currently in the works. The facility could also conceivably be used to read out emails or other personal messages.
In addition, motion recognition could see an upgrade, with a new predictive input tool that uses prior movement to predict your next motion.
Other snippets include a development application called NintendoWare, which emulates Wii hardware on a PC so that developers can sample parts of their games without having to load it to a Wii dev machine.
Meanwhile, Rumorreporter.com claims that Nintendo is readying the announcement of a Wii microphone, and that several voice-based games are already underway. It also claims that a voice-based Wii Channel is planned.
