Yes the low volume is unusual, perhaps all those who want out are done and no one game to buy in!
I doubt that we will hear anything following the indicative bid deadline as these things are usually on a confidential basis and given that they are incomplete non binding proposals there is a risk that disclosing level ( even range) of bids can freighten bidders off or mislead the market. So i expect we will be in the dark for some time to come.
That said I would ask all holders to have positive thoughts for a good outcome.
