They will be executable. Can't tell how I implicitly know. Provided other journalists I speak with can be trusted.
I can offer some logic behind it though. Directly downloading to the SD card isn't a very difficult update to implement. A few lines of code added to the Wii Shop channel and a graphical link asking to D/L to the SD card or internal memory.
What does take time is the executable coding and required DRM (and perhaps an SD card channel).
