I hope they have addressed the ridiculously large raw files they generate .. sometimes 20 megs for the NX10 ...

Unless you want lossy compression you aren't going to do much better than that.  A RAW file is 12 bits and has an embedded JPEG.  With no compression on your NX10 that is 14.6 MP * 12 bits = about 21 Megabytes plus maybe 1 or 2 MB for embedded JPEG.  Say 2:3 lossless compression ratio puts it down around 14 MB, plus a low quality JPEG for review and you are up at probably 15 MB.

The 20 MP sensor is going to be 28 MB uncompressed before you had in the preview JPEG.  This is not small, and not something you are going to be able to reduce much below 20 MB without lossy compression.
