Official shutdown time is listed as December 31st 2016, 23:59 Pacific Time.
Found via the NA eShop: this may be different in other regions. There's not really much lost here as it was supposed to go down in September (at least in North America), but it quietly got extended. The language seems to indicate that all the offline and local multi features will work just fine. I don't believe there is any reason it will be delisted, but that is pure speculation on my part. However, if you want to play the best sci-fi gun soccer spinoff of the year online (because Lucioball sucked big time), this is your last chance to do so.
Forget to cancel my EBF internet plan if old.
Thank you for your continued support. The online multiplayer feature for the Metroid Prime: Federation Force Blast Ball demo will be discontinued at 2016/12/31 23:59 PST. The discontinuation of this demo feature will not impact the online multiplayer feature available in the full version of the game.
