Will it sound similar to their other music? Will Jónsi still use the bowed Guitar?

Im sure there will be similarities but any band will want to change there sound for each album. Its like a whole new project, musicians will always receive bad feedback if they change or not. You can't please eveybody!

If you are interested in the Ros then there is another Icelandic act called Mugison who you may find interesting. I have the pleasure of being their support act in July. Look them up on YouTube, they have some great festival videos.
