Such a shame that Tabula closed down. They had some of the most interesting tech -- hopefully someone is able to pick it up someday. As someone who works with FPGAs, I think a solution like theirs is the only way FPGAs will become mainstream.
Altera took many of the employees (although quite a few are now at AWS) and it's rumored they also bought the IP. A lot of the core ideas will live on in Stratix, hopefully.
