We can all see the is clearly no chance of it happening at the scheduled time. I guess they see no harm in delaying the announcement until they absolutely have to make it but it is pointless; with some countries not expecting a peak in the virus until June,there can be no show until Autumn at the earliest.
I don't like the idea of everyone performing in their own country or having a show with no crowd, it is counter to what makes Eurovision special to me so I would definitely postpone over choosing either of those. But to cancel altogether would be harsh on artists and broadcasters who will already have invested time, effort and money into their entry and, greedily, I want another NF season next year so in the worst case scenario, those options are preferable to cancelling altogether even if I wouldn't be excited to watch it. The winning country should be given the choice of delaying until later in 2021 (say up until September) if that helps them to arrange hosting. Honestly, I see no reason why Eurovison must be in the Spring in general. If a far North country like Iceland or even Norway or Sweden were to win, it might make more sense for them to host in the Summer anyway.
