The prevailing thought that the GDSI deal is still being negotiated is not exactly true. Rontan has "killed" the deal. The ball is now in GDSI court. GDSI has hired lawyers (or is planning to), to see if a lawsuit by them has any basis for going forward.
If GDSI goes forward with a law suit, then I would say there is some hope for GDSI share holders. Until then, the deal is dead.
GDSI believes that it has satisfied or otherwise waived the conditions to closing and on April 1, 2016 advised the Sellers of its intention to close the SPSA and demanded delivery of the Rontan Securities. The Sellers, however, have notified GDSI that they intend to terminate the SPSA. GDSI believes that the Sellers have no right to terminate the SPSA and that notice of termination by the Sellers was not permitted under the terms of the SPSA.
At present, GDSI Believes they may have some basis for a suit. That does not mean they do. Their lawyers will advise them and then, and only then, will share holders know for certain if there is any hope. Until then, the deal is dead.
