They've been working on it, but it would be extremely risky for them to introduce such a radical technological leap in a vehicle that will need around a half million of them a year. If I had to guess, I'd say that GM will debut HCCI in the Volt (as a small 3 or 4 cylinder engine -not big V8). In addition to being low volume, the Volts duty cycle would make it almost ideal for the limited operating range of HCCI
