I think the bigger issue is all the customer code... If the new chip doesn't fully emulate the 390 / zSeries instruction set and architecture, then every customer would have to at best recompile every application and program they have. That maybe in the chip native or a layer of emulation code (aka: microcode), but it has to be there. Think of all those old COBOL programs that haven't been touched in years (decades)....
