well I'm not going to go any deeper into it than the reviews and follow-ups but the basic point is that it does use the same 256bit memory interface. in fact, that's a defining point of maxwell and why they're able to deliver such great performance at such a low price (by utilizing the same memory interface but cutting out some L2 cache).
claiming it had the same cache and ROPs as the 980 was the only part that could be called misleading. the memory interface is just straight up consumer misunderstanding and if you think the 970 should be every bit as good as a 980 then it's difficult to respond to your position on that: clearly one was $200 cheaper than the other and they're not the same card so, no, one can not reasonably expect that they'd behave the same...
If it used the same memory interface there wouldnt have been any need for NVidia to make a revised statement saying that they were wrong and that it doesnt use the same memory interface.
You quoted that very statement, if it helps:
As part of our discussion with NVIDIA, they laid out the fact that the original published specifications for the GTX 970 were wrong, and as a result the unusual behavior that users had been seeing from the GTX 970 was in fact expected behavior for a card configured as the GTX 970 was. To get straight to the point then, NVIDIAs original publication of the ROP/memory controller subsystem was wrong
