It is obvious most of the current Amiga users and devs are still on the 68K platform and most of the software is there also.
Why is it obvious? It is not so obvious to me at least.
AROS68K might just turn out to be far, far more serious competition to AOS4 and MOS then it's x86 version ever was, especially if Natami is released
Don't think so. Classic Amigas have just not enough computing power to be a serious competition for MorphOS and AmigaOS 4. Natami (if ever released), won't help much.
