Yeah.
Which is right I think. Given the nature of the atrocity of Hillsborough, it should not be rushed in to go any over 1:1. Without getting into the whole hillsborough thing, the idea of 'pens' that they had in the day was a complete disaster from the get-go. It will be all about space and over time it may get incraesed for those who have the required space to not even have a 1% risk of that.
I havne't read enough, but assuming BMD does have capability for 2:1, then its future proofed, hopefully relatively soon (years).
I'd worry about that once we know we are filling 52k every single week though.
