I have the RX100. I know it's not micro 4/3 sensor, but this puppy is amazing. It shoots like you said 10 fps and records 1080 @ 60 fps (with continuous auto focus). The camera is really small, it even fits my slim fit jeans pocket.
I also plan to use if extensively for snowboarding but to be honest I am a little concerned about it because I like to crash a lot. We'll see if it survives this winter
I highly recommend this camera, it has so many features and all are really useful. I am just too lazy to list them all here.
