This looks like quite a huge breakthrough, unless I'm missing something?

Looking at their methodology, it seems like it's more of an accumulation of existing good ideas into the one model.

If it performs as well as they say, perhaps you can say the breakthrough is discovering just how much can be gained by combining recent advances.

It's sitting on just the edge of sounding too good to be true to me. I will certainly be pleased if it holds up to scrutiny.
