That is the reason for the move to Z97. Z97 will work for Broadwell also.

Even as Intel launched its first Core "Haswell" Refresh socket LGA1150 chips, it left out two enthusiast-grade parts from the mix, the Core i7-4790K and the Core i5-4690K. Don't be misled into thinking that they're just multiplier-unlocked variants of the i7-4790 and i5-4690 launched today. There's a reason the two have be designated a separate internal codename altogether. Called "Devil's Canyon," the chips are made from high-performing dies binned out from the foundry, and placed on extra-durable packages with contact points that are designed for higher voltages, and a superior thermal interface material between the die and the integrated heatspreader (IHS).
Better packaging (mind the pun) isn't the only thing that sets the i7-4790K and the i5-4690K apart form their non-K counterparts, they're are also clocked higher. The i7-4790K ships with an out of the box clock speed of 4.00 GHz (the first Intel processor to do so), with a Turbo Boost frequency of 4.40 GHz. The Core i5-4670K, on the other hand, ships with a clock speed of 3.50 GHz, with Turbo Boost frequency of 3.90 GHz. The TDP of both chips is rated at 88 Watts, a wee bit higher than the 84 Watts the non-K chips are rated at. Expreview believes that the two could usher in a new era in CPU overclocking without breaking the bank over HEDT chips, and could be capable of running at clock speeds of 5.00 GHz, on air-cooling. Intel is expected to launch the two chips to crowds at Computex 2014, followed by a market release in mid-June.

The new Core i7-4790K CPU will have a Base clock of 4GHz, boosting up to 4.4GHz - this chip will have 8 threads (4 physical cores, 4 x Hyper-Threaded cores), 8MB of cache and a TDP of 88W. Its little brother, the Core i5-4690K will have a Base clock of 3.5GHz, with Turbo Boost up to 3.9GHz. It will not feature Hyper-Threading, so we're stuck with four cores. It will chip the cache down to 6MB, but contain the same 88W TDP.
Both of the new Devil's Canyon-based chips will support 1600MHz DDR3 RAM, too. The biggest thing to take away here is that the new Devil's Canyon CPUs will be the first CPUs from Intel that will have a huge off-the-shelf clock speed - 4GHz. With a Turbo Boost of 4.4GHz, EXP Review and now myself, will bring the "air-cooled 5GHz era back". 5GHz shouldn't be a problem on air-cooling, but if you were to use an aftermarket cooler - such as a Corsair H110i for example, 5GHz and beyond shouldn't be a problem. We should expect Intel to better unveil its Devil's Canyon chips at Computex, which kicks off in just a couple of weeks time.
