Nintendo will partner up with DeNA to develop Nintendo IPs for smart devices. No Nintendo IP will be off-limits and they will have a narrowed focus rather than releasing a large number of titles. Nintendo share value has seen a big increase since the announcement.
Nintendo's new console is codenamed NX
and will have a "brand new concept". It's not confirmed to be a next gen console or a replacement for the Wii U. More information will be shared next year.SourceSource
