to the latest drop in the rumour puddle over at Digitimes, Intel is set to release its next 8-series chipset in April 2013.
According to Digitimes' industry sources, Intel plans to relears performance and mainstream Z87 and H87 chipsets in April 2013. These socket LGA1150 motherboards will replace the existing Z77, Z75 and H77 chipsets with LGA1155 socket and will pave the way for entry-level H81 chipset scheduled for June 2013.
The 22nm socket 1150 Haswell CPUs are expected aaround the same time so motherboard manufacturers expect great interes for the new 8-series chipset simply due to the fact that new socket is not backward compatible. Ivy Bridge is expected to have its peak in the Q4 2012.
As always, take these rumours with a grain of salt as schedules tend to change.
