If it does run I suspect it will be a much smaller event. No one is going to commit to it untill the last possible moment. With it less than a year away and no one having a clue what the world will be like next year (economically and Covid wise)i It takes a brave soul to commit so much money to sending their company to show their wares.
If it does go ahead I suspect it will be a much smaller event, which in turn makes it harder for companies to invest next time. Just look at IPEX. 2014, it had shrunk so much, that by the time 2018 came a long it could not even fill a whole hall.
