I hate to bring up the K acronym (KGD) but the way that most companies are pushing along at Moore's rate is by stacking and vertical growth. Thus, KGD comes into play. KGD has been one of the persistant "on the horizon" big things for 30 years. I work for a BI and Test company and we are seeing significant movement in WLBI. This is the way to keep the Moore's law train rolling.
