I am actually really interested in next gen Rembrandt APUs rumored to be coming early next year. The top-end chip is rumored to use TSMCs 6nm node which comes with an 18% area reduction which should at least lower costs. It should also come with 8c16t of zen 3+ cores. Not sure of the difference between zen3 and zen 3+ yet but zen3 comes with 19% more performance over the zen2 cores in the steam deck so it should at least match that if not add a few more percentage points. As for the GPU I would think they would offer at least 8 RDNA2 cores. The steam deck has 8 cores and the current APU lineup has 8 vega cores. I wish we could get back to having 12 like the original APUs did but so long as we don't regress I think it will be okay. The memory subsystem likely won't be too different since the steam deck already uses LPDDR5 unless it was supporting LPDDR5X.
