WiiU will be around for another three years.
There is plenty of time for Nintendo to come out with games for it.
And I think Nintendo knows they need to transition to a new console with momentum from the last.
I expect Nintendo to experiment a lot with old franchises and new IPs with
the WiiU prior to releasing a new console. We can see that Nintendo is offloading its
work to third parties on games their internal studios are not interested to work on.
For example FZero. There might be a third party studio that did pick that game up.
Who knows what other titles are being worked on by third parties.
