Amongst all the above, I think the lack of focus peaking under video recording/movie mode is a real issue and would cause much inconvenience when using MF for video recording. This should be a hardware limitation I believe, e.g., not enough processing power or lack of additional hardware resource(s) for simultaneous processing and etc. Btw, my old NEX was capable to support this on day one.
Besides, the image engine of the K-01 is found to be lousy and inferior, at least when it is compared to the OM-D E-M5:-
