About a week ago Theta signed up Ultra.io (the gaming platform folks) which reinforces their Gaming stance. If you have not heard of Ultra they are backed by AMD (Processors & GPU manu) and Ubisoft Entertainment EA) which means they are not going away quickly.
Theta has alluded they are planning for Smart contracts release via Turing-Complete smart contracts (compatible w/ Ethereum VM) = Higher level Guardian Node(s)
Check back from time to to this post as I will continue to add items that I learn about for Theta Roadmap.
