I hope so!One of my biggest dissapointments in Oblivion was that despite the fact that the game had some ports they were actully useless since you couldnt travel anywhere.If you watch closely behind this rock arch you'll watch a harbour.So i am wondering if you will be able to travel to some remote islands from there...

Well the reason you didn't travel anywhere because there was only one real port town, anvil. Technically you could say the Imperial City also, but I don't see the point of only have two points that could use that travel system when you can just fast travel really.
Also, that picture I would say is Solitude.
As long as the fast travel is optional
Always has been optional.
