Funny thing about incumbent technologies is they suddenly become more robust after half-baked alternatives are proposed. But incumbent technologies do become more complex to survive to next round. Depends if they make enough money.
The memory makers again go in to a duel on the next gen memory standards. While there is an urgent call for cutting the power budgets there is also a demand for higher bandwidths which asks for more power. While there is plenty of bits that can be stacked in a space the whole debate lies in how to bring out the data from there. One way to reduce the memory contention is to compute the data on the fly but perhaps it is too much for the battery powered mobile devices.
