They certainly won't go bankrupt, but this will hopefully teach them a very well deserved lesson and if they learn from this they at the very least won't pursue the franchise any further. I'd say an absolute best case scenario is they give up on the home console industry as a whole, as without Metal Gear they don't have very many chips left as it is. But outside the console market they still make a considerable amount of money with various outlets such as their pachinko machines in the Japanese marketplace and more niche products such as their Yu-Gi-Oh division.
