Didn't they basically say a while back, in their view, that they've done everything they could with the series so what's the point of making more?
That's the problem. They haven't done everything they could with F-Zero. And they've continuously neglected Donkey Kong the past few years. Donkey Kong Country's 25th anniversary was cast aside in favor of celebrating JUST ONE YEAR of Super Smash Bros. Ultimate, and this year it's Donkey Kong's 40th anniversary but Nintendo hasn't done shit about it.
