Still waiting for the confirmation. From what I heard, the BCCI is still resisting the move, claiming that the situation in India will soon come under control. I am not sure how they reach such a conclusion, since cases are sharply increasing in states such as Uttar Pradesh and Karnataka. The BCCI is behaving not just foolishly, but they are also treating the ICC and other cricket boards with a lot of contempt.
BTW, the latest news from IPL is that Tim Seifert has become the first overseas player to test positive for COVID 19. He was a part of the Kolkata Knight Riders squad (which reported multiple positive cases among the players earlier). Seifert will undergo treatment at a private hospital in Chennai. Apart from Seifert, Michael Hussey (the batting coach of Chennai Super Kings) had tested positive previously.
This means we can't see the remaining of IPL 2021 if BCCI still don't want to move to other country.
