Yeah, so, this is a new trademark that's just emerged:
https://euipo.europa.eu/eSearch/#details/designs/008272074-0001
I want to begin by making it quite clear that
this has not been confirmed for a European market. The website that listed it is a European Union property office, but this does not indicate that the device will be releasing in Europe. In fact, some digging reveals that they've also listed several other versions that were all for the Japanese market. As such, I don't believe this will be an international release just yet.
It's also been noted that Italian is listed as a language in the trademark - this is also true for the Japanese versions; it's only indicative of the fact that the trademark representative (Studio Torta) is an Italian company.
I did some investigation into this to see what I could find and I ended up finding some interesting things, including more Tamagotchi trademarks from the same source. Firstly, I noticed that although this trademark only recently emerged, the trademark was first claimed in late August. This is also unique in the sense that it's the only one of these trademarks that lists the design trademark being trademarked
before the device's release. The others all claimed the trademark before release but filed the design afterwards. We'll come back to this in a bit.
Here's some more trademarks also listed by Bandai:
Tamagotchi 4U

Tamagotchi (2021 release)
https://euipo.europa.eu/eSearch/#details/designs/008272074-0001
Filing date: 27/08/2020 (Note though that this seems to be for the patent claim and not the document filing)
Announcement: ??/??/202?
Release: ??/??/2021
Additional info: Not filed by Wiz Co Ltd
There's been some speculation that this one could be another Meets / On release - the lack of Wiz Co suggests to me that it's definitely a new version.
Taking these dates into account, and considering that the new release was first filed several months ago, I'm predicting an announcement in the next few weeks - either later this month or early-mid January. Then we're probably set for a March release date, which coincides with the 17th anniversary of the Connection. So I guess I'll call it now and say I think it'll release March 20th 2021.
Some further digging for design trademarks reveals that there are more Bandai trademarks listed under a different organisation name:
Entama
https://euipo.europa.eu/eSearch/#details/designs/000455548-0001
https://euipo.europa.eu/eSearch/#details/designs/000455548-0002
Filing date: 15/09/2005
Release: 23/11/2005
Two months between trademark and release
Uratama
https://euipo.europa.eu/eSearch/#details/designs/000622576-0001
Filing date: 17/05/2006

Two months between trademark and release

https://euipo.europa.eu/eSearch/#details/designs/000660626-0001

Release: 23/11/2006
Nearly four months between trademark and release
TMGC+C
https://euipo.europa.eu/eSearch/#details/designs/001071831-0001
Filing date: 23/07/2008
Release: 22/11/2008
Four months between trademark and release
Tama-Go
https://euipo.europa.eu/eSearch/#details/designs/001196851-0001
Filing date: 30/09/2009 (trademark claimed) / 18/02/2010 (design filed)
Announcement: 22/03/2010
Release: ??/08/2010
They really strung this one out for some reason, but again the time between filing and announcement actually roughly matches the time between the announcement and the release
Here's something curious - the only international model here was one with a particularly long cycle, and another case of the design patent being out before the release or the announcement, unlike the Japanese models. It's been nearly four months since the new version first had its trademark claimed, so about 3-4 months until release makes sense, but I'll note that this is much more in line with the Tama-Go than with any of the Japanese versions. Maybe a hint at an international release after all? But we'll see.
Either way it looks like it's still around a month before an announcement and probably three months before release.
