Only if most Pentax cameras support it. It seems at this point there will be two classes of Pentax DSLR, the entry level early semi-pro bodies, (*ist-D), which won't support lenses with internal focus motors, and the advanced/semi-pro (K10D), and it's successors which will. Since most people will probably buy a K100D, K110D or *ist-DL rather than a K10D for the foreseeable future, lens manufactures will have to support both or lose out on a significant share of that market.
