Cantsin, I see your concerns. But with sandisk extremeextreme uhs-ii the nx1 is now capable to write up to 6-8fps with buffer full (endlessly), again raw 6k. How long for a card which is 2-3x faster? And ssd are already much faster than this. Ok for the audio, it can be a mode with no audio (to be recorded with separate device). I'm really convinced that the hw of nx1 could do it now, but we won't ever know, unless some magic lantern like fw pops up.
