Most definitely I will wait and see what happens with the next firmware. The main reason I sold the 7D was to go full frame for low light ability. I was hoping the new 5D wouldn't have this same af issue as the 7D. But some have said that the af is so good that visual confirmation of lock is not necessary in single shot mode. Which is good because I can't have my subjects distracted and bothered by the big red lens barrel light coming straight at them like some kind of sniper. Not good. I was very surprised when I saw the you tube video of this. I don't think that can be fixed with firmware. Anyway, if the black af points are going to be dim with fast prime lenses then that might be a problem.
