Although this is not official yet, it looks like Samsung has already disbanded the entire team that was working in its Austin R&D center to develop architectures and designs for the System LSI division so next-gen Exynos chips will — most likely — use solutions developed by ARM instead.

:o It never occurred to me that this would be possible. What's the point of Exynos then?? Just a backup from Qualcomm? I don't think Qualcomm would make any stupid moves against Samsung, since both Apple and Huawei, both big customers, are trying to move away from them
