I realize that the Amiga Community is extremely splintered at the moment and there are very few 68K coders left. Having said that, I could see AROS becoming the de facto WB updates for the 68K amigas because:
1. It's open source.
2. Being open source, that means there are no ugly legalities that seem to snuff any possible future developement of 68K.
3. Hardcore AROS Devs are softies when it comes to the subject of 68K Amigas.

AFA is an excellent initial bridge between AROS and it's roots. Question is on the side of the 86K community and if they are going to come together as a community to support AROS and it's developement. I will give a fair warning for chosing AROS for future WB developement, it's like being on the wagon trail heading to the wild wild west. Lots of brush to get through with plenty of heartaches along the way.
