don't worry about it...select the focus later
Not sure if any one you have seen this but I signed up to "reserve" a camera a month or so ago and just got a newsletter in my email.
I'm still on the fence what this will do to photography. I mean who would even have to think anymore. If you could get this technology to the level of quality of a medium format camera and have it be priced where entry level dlsr cameras are right now it would almost make pro's obsolete. I know there will still be a need for people with an "eye" to get a certain level of quality out of certain type of photography but...a HUGE portion of what we would call pro level photography could be wiped out. Who needs a pro on the side lines if someone with a camera like that just spraying away at the action and then later select the focus and have that level of quality. Because let's face it- the first dlsr I had(the 20D) compared to what people have in their hands now is crazy. Imagine what could be in peoples hands in even 10 years from now...
