Please, make it available for purchase again.
I understand, that there are probably strong reasons to stop selling your products because of this disaster, but I think there are some people like me, who want to buy some of them in their current state, even without any hope for future updates.

Some products are still available from third-party retailers: https://www.google.com/search?q=sonar+platinum&source=lnms&tbm=shop
 
Did you have a specific product you were looking for?

(double double toil and trouble)
