So here is the word on the street, which we all know is reliable and not fake news...
Still a soft release date of late spring 2018. RE is likely going to keep the initial price point below $400.
The colors may change but the current production version does not have the shackle for tending, it is a smaller integrated hole on one of the aluminum spine plates.
There are some smaller changes I can see from pictures that have been shared with me from the expo, namely the upper eccentric pin has changed shape, likely to help with wet rope, and a general compatibility with more brands and sizes of rope.
More tid bits dribbling in...
