I don't think this is the case. We have seen MIPS and ARM appear, and all sorts of ISA extensions (like NEON). Amazon even offers non-x86 machines now!
The old mantra "without software no one will buy your hardware" is no longer generally true. There are lots of programmers now days, and as long as your new chip can show improvement in one area, someone may use it. We've even had chips which execute Java bytecode directly!
