Alec White of White Industries frotm Petaluma, California teamed up with Chris King and some other collaborators to develop the T47 bottom bracket standard, a threaded shell that can handle a 30mm spindled crank. In addition to eliminating all the problems of press fit 30mm shells T47 can accomodate wiring for electronics that can't fit in a standard 73mm shell. The idea is to coexist with 73mm threaded and start edging out pressfit. Word is that some of the big companies are interested.
