Sadly I don't think Universities can promise anything at the moment and have to be prepared for all eventualities. At the moment in the UK many restrictions are being lifted on July 19th. However it is an experiement and we don't know how this will go, especially as Autumn approaches. Nothing is guaranteed. There is already talk of more lockdowns in Autumn - Winter. I genuinely believe universities do want to do more face to face teaching but I don't think they can make guaranteed promises. Many are preparing for a return to normal but at the same time realise they may have to revert to online. Personally I think things will still be unsettled this winter but I am staying optimistic that things will be better in 2022.
