Should @TalonMan add an option to change what is the shown unit of VG$? I probably would also switch to rupees. Gil, Zenny, Macca, Bells, Poke would be alternatives. Maybe a premium feature for supporters.

2021 GOTY.

That'd be awesome!! :D

This game will come out before Metroid Prime 4. So, I would say, fall of 2020

Holiday 2020 makes the most sense imo.

Imagine if it's late 2020. We could have games from 5 different studios who previously won GOTY releasing in 2020 if that happens. Will be the most epic GOTY race of all-time.

Voted early 2021. A little extra dev time compared to a late 2020 release, it doesn't need a holiday launch to sell, plus that will still be in FY 2020.

I'll go safe and say early 2021

Mid to late 2021 seems to be the most logical timeframe.
If it was 2020 they would have announced that information and 2022 might be unrealistic because they utilize the same engine used in botw and can reuse a lot of assets.

Nintendo is targeting the second half of 2020, because otherwise they wouldn't have made the announcement at this time. Switch has an abundance of upcoming first party games in the near future and if Zelda couldn't possibly be ready in 2020, they would have used a different team's game to have a big title for people to look forward to. Remember, the teams that released MK8D/ARMS, Splatoon 2 and Super Mario Odyssey in 2017 could all have their next game ready in 2020, but Nintendo picked the Zelda team for this announcement.

Considering that Pokémon was/is a holiday title in 2018 and 2019, it's highly probable that 2020 will be a year without Pokémon. Good chance that Zelda will be positioned as the big holiday title, so November 2020 is the most likely month. While a delay is possible, I think this time the Zelda team will deliver on time.
