will there ever be NEX 7 firmware update? :(

I'm not sure what support you need? Just to change the firmware for the sake of changing it?

So far, I've seen few things which merit firmware updates -- no persistent problems on the forums that aren't functional changes. The two consistent wishes are functional changes: changing AEB might be good but it's a known and advertised limit so the way it works is the way Sony told you it'd work, there is no flaw in the operation. As far as the video button goes, I suspect they'd get more support calls as people accidentally enable the restriction mode and then can't figure out how to activate the video.
