do you think they will announce they have received, for example, 3 bids from various parties and move into round 2 bidding?
No, I do not.
They will probably get in a room and get one of those fast talking auctionares, just like they do cattle:-)
If it's news from the company, don't expect any word until a final bid is accepted by the Board. The only other "news" that we hear will most likely be leaked, just like the bidders named and the "after Labor Day" comments circulated on the news.
