Samsung will launch the next SoC in the Exynos line at CES 2014 on the 6th January in Las Vegas. The information comes as a teaser but there is nothing to make it deniable possibility as it was SamsungExynos (@SamsungExynos) to express it on their Twitter account yesterday. The new Exynos SoC is expected to feature a Trure Octa-Core approach from Samsung and there might be a new 64 Bit processors somewhere there too. The Tweet from @SamsungExynos is a rather confusing one though and is quoted as :
#CES2014 is right around the corner. Are you ready to #UnlockExynos?:
If you put a though into the UnlockExynos part of the Tweet then you may assume that it has something to do with the current Exynos 5410/5420 Octa-Core chips that are not capable of Heterogeneous Multi-Processing (HMP). The HMP simply is a concept that allows all the eight Small & Large (ARM Cortex A9+A15) cores to work Simultaneously for a “True Octa-Core” experience on the Galaxy S4 & Note 3. Additionally there is an information that suggests that the Exynos 5410 present it the Galaxy S4 does not have a Hardware to support the HMP so all you Galaxy S4 owners might be out of luck there. With only a little more than a week for CES 2014 there is still a lot to expect from Samsung, The Galaxy S5 
perhaps.
