The Continental looks like a proper early 60's back road scratcher and will probably only appeal to the grey haired or no haired baby boomers who can't fettle their own Commando or Bonneville.
There aren't any millenials who are going to get all giddy over something this stodgy. RE have a fan base that seems to support them well enough to develop new bikes and I hope these new parallel twins are a huge success.
The Interceptor is a lot more standard in its appearance and will appeal to the same blokes of a certain age and experience who remember when the original Interceptor really was something special.
