Unfortunately, Microsoft has not provided any information regarding its features, but what is certain is that the price will not change like the price of the old product. Microsoft continues to implement a one time purchase with a support period of 5 years. However, according to news circulating, it is possible that Office 2021 will support a dark version or dark mode. Not only that, reportedly there is a new product called Office Long Term Servicing Channel (LTSC). This version is reportedly intended for commercial or corporate customers who need long-term Office services.
