Plans from the Wii U's video technology provider could suggest new features on the way to Nintendo's system.
The Wii U currently has a one to one chatting system that uses the GamePad between two friends on the system. Whilst it's clear and simple to use, a game has to be stopped to start chatting.
Video, the folk who worked on the system for Nintendo, have a PDF on their website that outlines various features that seem to be considered or in development for Wii U including Miiverse and multi-person chat - as spotted by NeoGAF.
Focus on social networking around gaming
Now: video chat in Miiverse
Next: video-powered game experiences
Chat today, conferencing soon
Next: multi-party conferencing
Extending to mobile devices soon
Now: between Wii U consoles
Next: between Wii U and mobile devices
Nintendo did say that Miiverse and mobile connectivity are one of the areas in development for future Wii U updates, so it's likely that some of these features would popup later on in the year.
Have you used the Wii U video chat app - would you like in-game chatting and videos to be incorporated into Miiverse?
