Falling io price to encourage another bidder....???, page-8

Yes - have no broker who follows this stock now since buying in ages ago -Could someone PLEASE elaborate on this - i.e. if one signs and sends back BCI doco - then a higher cash offer comes in from elsewhere prior to 30th September - after holders have committed to BCI - what's the story then?
And does anyone seriously feel there may be a Chinese offer - and if so, when? (i.e. woulkd BCI then sell into that offer later, assuming they have the correct share holding if such occurs? Assume I'm right - that this is a bird in the hand better than one in the bush scenario -

Is this totally being controlled by current IO price?

Would appreciate some knowledgeable views. (Realise it won't be investment advice!). Thanks in advance. Cheers.
