There have been many rumors about a Wii HD for quite a while now, even analyst Michael Pachter says he knows its coming. Recently, Nintendo had a quarterly investor Q&A where Nintendo’s president Satoru Iwata spoke about their next system after the Wii. Iwata said, “If asked if making the Wii compatible with high definition — just making it compatible with high resolution — will get players throughout the world to buy it, I would of course say, ‘Do you think it would sell with just that? It needs something new.’”
In short, Iwata says he thinks the next Nintendo system would need more than just high-definition. HD would definitively be something great in Nintendo’s next system and besides a hard-drive and good online multiplayer, there are most likely things that will package with the system that will spark many peoples interest much like the Wii did. Maybe that systems main controllers will be vitality sensors (sarcasm).
