I agree in the current situation. We start to hear more and more athletes saying IOC doesn't take the health of the athletes serious. Stefanidi has said she puts her health at risk by training and prepare for competitions. I have also read some gymnasts don't like the idea of touching the same apparatus in a training facility.
Also, former British rower, Matthew Pinsent tweeted, this:
It's a very difficult situation for all parties involved in this ongoing crisis. As I can see, many here on the forum here wouldn't mind Tokyo 2020 being postponed if the crisis continues like this for the next months, both for the security of the athletes' health and that the qualification process would be too difficult to complete.
I'm curious too see if we will some top athlete come out and say that they will boycot the Games before the end of this month? If some do, and the situation get's better by May, will the athletes then say they will participate despite of what they said one or two months before?
Beside all the questions about economics, IOC and the organisers are in difficult situation as they and most of world, including health authorities, don't know exactly how this crisis will develop. If IOC comes out this month and say the Tokyo 2020 will be postponed with one year then that decision will likely not be changed.
I still think IOC, the Japanese organisers and the majority of athlete still hope the Games will be held this year. Of course I don't have any inside sources to verify this. I could be wrong and Thomas Bach and the Japanese prime minister are the only one who truly believes the Games will run as scheduled.
Personally, I think IOC and the organisers should wait to mid-May, around two months before the Olympics begin, to announce if they postpone the Games as this situation changes daily. Lastly I would like to say, I do not think the situation has been stabilised worldwide when we come to mid-May, so I think the Tokyo 2020 will be Tokyo 2021. But it's easy for a young man like me with no power in the world of sports to come with my speculations about such a big decision and change them as I please. IOC are in completely different position.
Bear in mind, most of the above are mainly own personal opionions and speculations, so take it all with a grain of salt, as I'm in no way trying to act like an expert on the matter.
