Seems more liekly they've just caught up with the news from 4 weeks ago.
Gotta wonder when you get this sort of stuff getting published in the dailies whether its information ... or misinformation.
Now everyone "knows" its BHP and its a TO what will they do if they cant get a deal and the SP relists... is the SP gonna go down now everyone knows BHP want it?
Good luck trying to put the genie back in the bottle.
