Talking about Star Fox Zero, Nintendo's Shigeru Miyamoto said Star Fox 2 should remain a part of history.
Fans of the series have been keen to see the cancelled Star Fox 2 officially released to the masses. Unfortunately, the chances of that happening are rather slim due to numerous reasons. A finished, working copy of Star Fox 2 does exist, so there are technical possibilities for Nintendo to be able to plop it on the Virtual Console, perhaps.
When asked during E3, Shigeru Miyamoto felt that "it's ok for Star Fox 2 to just remain a memory" and how elements of that game - including the Wallker mode - are being realised in the new Wii U game, Star Fox Zero.
Should Nintendo release Star Fox 2 at somepoint?
