Surprised that Xtrabytes isn't mentioned here at all. The project gives development updates on the 21st of every month, in addition the developer answers 7 questions on the 7th of each month (today!).

The project aims to become a programming language agnostic, dApp platform with 10.000 tps. They are currently in the process of securing three patents for their technology. Once these have reached "pending" status, the main net will be released.
