In the meantime, we know absolutely nothing about the actual proposed replacement - no real building plans, no list of exhibits, nothing. The fact that they are even tendering an interim site suggests to me the real replacement won't happen for a long time - and probably trying to use elapsed time and faded memories to set the public up for diminished expectations.
Perhaps we should put a casino, pot shop and bar in there - it would probably solicit more interest from this government. Proposed exhibits/retail outlets:
EtOH!
Munchies
Everyday probability through gambling.
