I seem to remember something about the site being redeveloped, so that 2020 would have been the last year there.
There was then talk about whether that was still the case last year, but obviously Covid put back any development plans. When they mentioned big changes/surprises, it made sense that this could be a move, as there was still plenty of time to plan that.
With the fifth day those changes may already have come, especially as time passes you'd think someone would have picked up news on any redevelopment plans for the site.
