Every developer in the universe is showcasing footage of there game way before release even nintendo.
There is no excuse here, we all know the buggy shit show there games are on release. this game is in no way done even remotely or else they would have showcased some shit. Hell even elder scroll 6 or whatever had some footage even if it was fake as hell and isn't releasing for over a decade later.
If your game is pretty much done, showcase atleast some part of it instead of shit art that says nothing.
I think these clowns at bethesda are trying to maximum bait pre-orders like they always do so they cash in on the hype before it all crashes down again.
Plenty of other devs drop trailers that end up looking nothing like the finished game years before launching a bug-filled wonder. The difference with Bethesda is that their games don't have gameplay reveals until the summer before they launch and the trailers are always 100% true to what the final game delivers. It's always the same, a production trailer showing a cinnematic which cuts to a sizzle reel of in-game footage followed by an more in-depth gameplay-only trailer.
Morrowind - E3 2001 - First public showing - Game launch date "late 2001" delayed to May 2002.
Oblivion - E3 2005 - First in-game footage - Game launch date Nov 2005 delayed to March 2006
Fallout 3 - E3 2008 - First in-game footage - Game launch Oct 2008
New Vegas - E3 2010 - First in-game footage - Game launch Oct 2010
Skyrim - E3 2013 - First in-game footage - Game launch Nov 2011
Fallout 4 - E3 2015 - First in-game footage - Game launch Nov 2015
Fallout 76 - E3 2020 - First in-game footage - Game launch Nov 2018
Each of these were accompanied by long in-depth gameplay trailers at their respective E3 reveals and each launched that same year. In each case the footage shown was identical, for better or worse, to what launched later that year.
Bethesda has always done things this way and it seems to have done well for them. They release gameplay footage the summer before launch. Generate maximum hype and have the game available before the holidays and typically the games are successful. The only times this didn't happen the games were delayed and the last time that happened was Oblivion.
