If you call it amiga news because MorphOS runs on the classic, then we already have by your definition modern browers like firefox, konqueror and so on running just fine on Amiga already.
Yeah. These appz run fine on hardware which has been AMIGA branded, but hosted by an alien OS (linux BTW)
Sputnik will run on an amiga like environment and along side with AOS and MOS appz.
In fact, if you run MOS on a classic, you will not notice is the system you´re using its called MorphOS or AmigaOS, since they are step-brothers ( well, except MOS will be faster than AOS 3.x by category )
