We all expected the next Qualcomm flagship processor to be the 5nm SD888. Qualcomm has slipped in a beefed-up version of the SD865+ – the Qualcomm SD870 5G and its likely to be in most near future flagships.
The Qualcomm SD870 5G (website here) is not a new design. It is a 7nm SD855+ SoC with the A77 core increased from 3.1Ghz to 3.2Ghz. As far as we can tell, the specs are otherwise identical.
