Depends on what you mean with 'lightmap' - if you mean the classic Quake 2-style slapping of colored textures on top of diffuse textures, sure, probably that wont be much of a sight in 10 years. However even nowadays (or years ago, really) most lightmaps contained more than that (e.g. at minimum you'd need directional information) and i doubt raytracing will get rid of the idea of precalculating lighting information per surface, especially as raytracing hardware becomes more programmable.
