I still don't quite believe those specs. Why make a slightly bigger sensor instead of using the same one as the S100? Really, 1/1.5" is just marginally bigger and won't give any real advantage in S/N ratio or control over depth of field (especially with slower lens than the smaller and cheaper S100). But it it's a 1.5" sensor (or 1.5 crop factor) then it means APS-C size. Again, why not use the same sensor that they use for DSLRs in that case? And with such sensor, how to make a 4x zoom starting at f/2.5 that's small enough for such type of camera? I think we should wait for official announcement to be sure of what this is.
