Wii U exclusive Star Fox Zero has been delayed into 2016, following an eleventh hour decision by top designer Shigeru Miyamoto.
Star Fox Zero had been due to launch on 20th November - which is still two months away, although physical copies would now be needing to begin physical production and shipping.
Nintendo explained the decision with a statement from Miyamoto, posted to its various social media channels.
"I made a big decision last week," Miyamoto wrote.
"We have been developing Star Fox Zero for Wii U with the aim of releasing it this year. Although we felt that the development had been progressing well, we now believe that we will need a little more time to work on areas such as the unprecedented discovery that we want players to experience in the game by using two screens, and further polishing the level designs and perfecting the tone of the cut scenes.
"While we have already reached the stage where it would be technically possible to release the title in time for the year-end holiday season, we want to polish the game a bit more so that players will be able to more smoothly grasp the new style of play that we are proposing.
"To the people looking forward to the launch of the game this holiday season, I am very sorry.
"Star Fox Zero is going to bring new game play and experiences that take it far beyond the framework established by Star Fox 64. All the members of the development team are doing our best so that the final product will not betray your expectations. And the game will not be delayed for a very long time - we're aiming to launch the game in Q1 2016. Please stay tuned for further announcements."
We played the game's last press build back at E3 and came away with mixed feelings - so maybe a delay will be no bad thing.
"It's perfectly stable and polished, of course - this is Nintendo after all - but it still feels like a rough assemblage of freshly-coded ideas," Oli reported in his Star Fox Zero preview, "and some are working better than others".
