How about Polis or some other entity taking a controlling interest?
In such an event as much as half of the outstanding shares would be tied up in long term positions and then the potential to be taken private would be obvious to the market.
To see Polis or any entity make a move in that direction would indicate tier 2 offers one heck of an opportunity. If they can establish such a position up to about $1/share would give us a better peek into the value of the remaining litigation.
Remember EDIG is becoming a cash cow and it is merely a matter of buying that cash for pennies on the dollar.
