So I really am forced to wonder..... it is all speculation for now.. but if Sony does indeed start building mirrorless A-mounts.... Then will future A-mounts be a backwards step in autofocus, just like the dSLT was a backward step in high-ISO performance.

Would slower but more accurate be a step backwards?

Depends on your priorities.  To me, focus accuracy is never an issue if you have enough time.  If you have all the time in the world, you can get the focus accurate eventually.  The wonderful thing about a good dSLR is focus SPEED.  The able to get that accurate focus FAST.

So to me, if I lose the focus speed, it would be a huge loss.
