Amiga Inc have already stated that they are not interested in supporting the developement of a browser that would run on MorphOS. They have web technologies expected to be delivered in OS4.1->4.2.. This included basic HTML and Javascript support. With those technologies, it is assume someone else will build a browser useing those components.
Such as Aweb? or IBrowse?
I think fleecy may have said this in one of the interview thingos he does at Amigaworld.net
