digitalversus put up some sample comparisons of a pre-production NX-1, the Sony A77II, and the Nikon D750 as a guessing game. The answers are on the french language version of the site:

From the samples given, the BSI sensor looks pretty good. Better than the Sony crop, at least.
RAW files are here, although I couldn't open them in ACR, of course. Maybe someone with one of those weird RAW converters I'm not going to bother to download and install can open them?
