Maybe have a look over at the AVS forum & see if there's any references to the 1016 fw there. There's been about 3 fw updates to date with no-one reporting any issues. I think Samsung learnt a lot about stuffing around too much with fw last year with the C7000. Up to you though. I'm not updating atm as I have no issues and would prefer to know exactly what the fw update is addressing. I think os they're actually up to about version 1020. Samsung Australia is a little behind, which is not necessarily a bad thing.
I see there is a new 1016.3 firmware released October 7 too. To try or not to try...
Let us know how you get on.
