Intel decided to quit the PC motherboard business by shutting down its Desktop Board brand. To company will begin shrinking its motherboard product line with the arrival of socket LGA1150 Core "Haswell" processors, and eventually leave the market within 3 years. One can draw three distinct inferences from this move. First, Intel's Desktop Board lineup is too bloated, and the desktop form-factor is on a rapid decline in relation to the rest of the PC industry. Second, with the emergence of new high-volume brands in the motherboard industry, Intel is finding its lineup out of place.
Third, and more interestingly, this could be a move by Intel to pacify other motherboard vendors about the impending transition of a bulk of the motherboard volume from changeable CPU socket to hardwired BGA, which is bound to happen in a couple of years from now. Other vendors expressed apprehensions over the transition to BGA believing such a more could make Desktop Board put them out of business. Intel's Desktop Board team will instead spend resources in developing new form-factors such as the NUC.
