The end game for VSTA is in sight. The other points I would add to your analysis is the decisions that Platinum faces. They will look to protect their investment and if the II article is correct understand how to maneuver in distressed situations. I still say they may force a pre-packaged bankruptcy if they think there is value here and sell the IP to another company.
The odds of fresh cash from a new investor coming into this mess are extremely low. And as you point out, you need money to get an audit and you need audited financials to get an investor. Good luck with that.
