Microsoft released its Windows 8.1 preview to the public on Wednesday and it remains to be seen how users will respond. As it turns out, however, the PC industry may be poised to slow its current slide regardless of whether or not Microsoft’s big software update manages to drum up some excitement. According to unnamed industry sources speaking with Digitimes, PC chip suppliers are expected to see shipments pick up in the third quarter as vendors prepare to launch new notebook computers powered by Intel’s Haswell chipsets. The report claims PC makers are expecting sales to improve in the U.S. and China beginning in the third quarter, and component suppliers including Richtek Technology, Global Mixed-mode Technology, Elan Microelectronics and Egalax-empia Technology will begin to see revenue increase significantly beginning this month as orders ramp up.
