I think the P&S is on life support at this point. There are some really great ones out there, like the little Sony ones, but for the most part a phone can do about anything a P&S would just as well if not better. Phone cameras really are phenomenal these days.
I don't see interchangeable lens cameras going anywhere, although DSLRs will probably be fading off into the sunset into the sunset in the next few years except maybe for some niche uses. MILCs are getting a lot better, but I don't know know if they're quite ready to replace action cameras like the D6 yet. It's a matter of time, I'm sure, but I know Nikon(I don't really keep up with Canon) has released some phenomenal albeit specialized and super expensive lenses in the past year like the 120-300mm f/2.8.
I've yet to see a P&S that can match a DSLR or good MILC in focus speed and shutter lag. Newer ones are better than ever, but the motivation to improve them just isn't there. MILCs use to have issues with focus speed, but from what I've seen that's gotten a whole, whole lot better. Contrast detect is focus should inherently be more accurate than phase detect, but of course is slower. If I'm not mistaken(and forgive me if I am) most of the higher end MILCs use phase detect to get close and then do the final tweaks with contrast detect. I'm not sure if there's ever been a P&S that used phase detect-most of the old film ones used active focusing, which is fast but has a lot of lot of limitations.
