Not soon at all, advances in technology won't change the laws of physics. Light will still need something to bounce off of. Remember, all out tech advances lately have pretty much been refinement. Free-form projected holographic displays aren't even around in a rudimentary form. Doing this will take some nifty tricks of physics that we haven't even begun to toy with yet.
It will happen eventually, but not in our lifetimes.
