A statement from Executive Producer, Daron Stinnett;

Hi Everyone,

I just wanted to step in and give everyone a quick update given all the rumors circulating. We are now in the process of finding a formal publisher for STO, which involves conversations with a variety of parties. We have been working on our business model for some time and once we establish a publisher, we will work with our new partner to communicate exactly what we are building - something I know all of you have been waiting a long time for.

There was also a report about PE.

We'll keep you updated as this story develops.
