My personal opinion? One size won't fit all. There will be a mix of batteries for different purposes. Due to cost factor SDD i think will be limited to high luxury or military functions. The other point is the million miles battery will have it's niche market in places with smaller travel distances, such as asia/ or city driving. Due to lower range. In the west/country areas or it's quite possible to sacrifice cycle life for higher range by increase the voltage. It's a catch 22 but as they say, different strokes..I do know one thing though, we have probably the best technical board you could want for EV I believe Novonix will lead the way with many surprises in innovation.
