A rumour that has originated on NeoGAF suggests that Nintendo started working on a brand new platform in early 2013. The platform is supposedly a handheld, which would make it the successor to the Nintendo 3DS. This is a rumour, but it’s likely that Nintendo has already begun planning the followup to the successful 3DS console.
Almost certainly off-topic, but I don’t quite want to make a new thread, because it would go to shit quickly. Also, I’d need to post a source, and I don’t really want to get people in trouble. Anyway, Nintendo apparently started working on a new platform in early 2013 and has already selected a vendor for the SoC after talking to several potential candidates. The SoC might be based on an existing design, but will be changed to fit Nintendo’s requirements. I assume it’s for their next handheld, though.
