The number of interested parties itself is a source of confidence. I may be being too optimistic or hopeful here but I have a feeling what we are seeing now is a lot of people chancing completing a sale quickly while their is still financial uncertainty and the stadium is incomplete. And I think the "big boys" are waiting for the 777 stuff to be fully resolved and the stadium to be completed.
The downside of this theory is that it means we have Moshiri until at least January, the upside is that we'll be sold to people with the actual means to invest into the club and the area surrounding the stadium (and hopefully the Goodison legacy too).
