I think they would be better to postpone it to November time and do it when JESC is on, and rest JESC for a year. This would give breathing space to see how Corona Virus develops and lets them come up with a back up plan.
Of course there are downsides to this - availability of both arena and artists, and it doesn’t give much time for the 2020 winner to prepare, especially if it’s a first time winner.
I’m not convinced the satellite option works as there’s way too much chance of things going wrong - with 41 countries chances are something would fail at some point, whether that be the satellite link, audio, etc.. Plus countries like Sweden and Russia would have a massive advantage over ones like Moldova and San Marino with their facilities And how can they ensure rules are followed ie. no backing singers on tape and so forth?
No audience seems the best option but even that has its flaws - some of the artists might not even be allowed to leave their country, if restrictions are put in place! However we’ve had EBU officials saying the audience is pertinent.
It’s a massive headache and I don’t envy the EBU and I can see why they want to go business as usual for now but I think the decision is probably going to be taken out of their hands eventually. Sweden has just banned all public gatherings over 500, other countries have limits of 1000. Its only a matter of time before the Dutch government bring in something similar.
