What changes to Lovelace (40 series) µarch do you speculate Blackwell 50 series will bring?

VRFs have remained unchanged since Turing, L1 and CUDA cores unchanged since Ampere.

Is any changes to non RT and tensor core logic like data stores and CUDA cores likely with Blackwell and if so what could it look like?

Or will NVIDIA just continue to double down on RT and tensor without changing other things?

I well aware that no one knows for sure and we'll know in 1.5 weeks time. But it's always fun to speculate and this is an open invitation to speculate on 50 series, not based on rumours but based on potential changes to the microarchitecture.
