Your first guess seems more reasonable - 3D.  TI has recently demo'd
what seems to be workable 3D technology - I suppose one will want bits
on the order of 1.5K by 1.5K by 24 bits deep, then 1K or so of Z axis.

But I suspect that the next (NeXT?) major growth area of man/machine
interface is sound & speech.
