Sony RX100 vs Samsung EX2F

Yes and no, I mean theoretically had Samsung done with BSI technology to 1/1.7" what Canon did to 1/2.3" it could have done much better against the RX100. The said truth is they didn't, at base ISO it outputs if anything worse than older 1/17" CCD and CMOS. Don't get me wrong, I'm not saying it ever could have matched the RX100.

If Canon came out with a 2/3" with BSI, and their earlier expertise panned out, it could possibly, perhaps give the RX100 a good challenge. However thats not likely to happen, as only Fuji seems to appreciate that sensor size.
