I think Tron has shown it certainly intends to fork asap, as Roy Liu has repeatedly indicated they reckon reducing powerdown time dramatically necessary, and from various statements regarding their plans for Steemit, Inc., and Steem. It's also been reported to me that Sun has offered proxy.token voters things that could only be provided by a fork.
There's little doubt in my mind that Tron will undertake a fork asap.
I appreciate your courteous reply. Thanks!
