I think a 650 has limited appeal...in this modern era its just too small for anything other than a commuter IMO. I know that some will disagree, but I also have a 750 twin and it is too small...I like riding it and it is a joy with its lightness, balance, and handling....but I grew up with them. To the new generation, loading up with a pillion and briskly accelerating up a long steep hill/mountain in top gear is an accepted norm, our classics won't do that and neither will the RE.
Granted it will be competitively priced, but for the same $$$ you could get any number of 'as new' modern bikes with as much or more to offer. The RE will only appeal to a small niche market which is also contracting by the day.
