This is an important thing that a lot of people are forgetting. Crop mode seems like a great way to get many of the benefits of FF (much lower noise at high ISOs, etc) even if you don't have FF-compatible glass yet.

I'm not sure this is the case when one is using only a crop of the full-frame sensor. But doubtless someone on here will know.

I am curious about this as well.
It would only have lower noise at high ISOs in crop mode if the sensor had lower noise at high ISOs in APS-C format. Otherwise it would be the same noise as the equivalent APS-C sensor.
To clarify, if the FF sensor is the larger version of the k-3 sensor or the k-5 sensor, the crop mode ISO performance would match the k-3 or k-5 respectively.
