Have just ordered it while watching paid reviewers.
Wonder who will be the first to start whining here?

And like I always says, DJI do listen to us.

What's new and we requested:

Can adjust sharpness
Noise reduction on/off in low light
Gyro Data

Curious as to what sold you on being an early adopter?  I'm tempted but going to wait until I seem some unbiased user reviews.  

I just want to be among those getting it first, just like I did with OA3 last year.

Enough said.    Hopefully, it doesn't have the early issues that the OA3 had.

I hope not that too.
Have updated my main post with what's new in firmware.

I`ve lost my OA3 in the past winter, when skiing in a resort.... but it started with problems (focus problems..), and ended whit a problem (lost)... Just it wasnt my camera haha. The good news is that the batteries from OA3 are compatible with the OA4 and if the problem whit the lens is solved i can trust to order only a camera again.

Sorry to hear that you lost your OA3.

It do looks like it is just the internal that have changed + firmware. So battery from OA3 should work.

Great to hear about the sharpness setting. Right now all the footage I've seen so far looks far worse than anything from the GoPro 11 in that regard.

Is it possible to adjust sharpening and noise reduction like on the Mini 3 Pro from -2 to +2?

True, and I heard it have 5 different settings compared to only 3 on other brands

Max bitrate in livestream mode? Always 1080 6mbps ?

Does it support RTMPS in livestream? If not, that's a deal breaker for me.

Just read your updated main post.  That's a good start to the upgrade over OA3.  

Anybody know if it uses the same batteries and magnetic mount as the Action 3?  The battery specs look exactly the same, but it would be very un-DJI like to have 2 devices share the same components!

Well as most know I love my 2 Action 3's. Will be keeping an eye on this one

99% sure it does.

But bigger sensor will consume little more power, so could be they will release later on a more powerful battery if possible. But for now I think we are good.

According to the DJI Store, both the batteries and the accessories are compatible.

Yes it does both of them.

Action 4 gives us Gyro data?

Yup it does

I tried it today in shop, and compared it to A3. Cannot really see the differences judging just with the display. The only thing that was striking was that at 100% display brightness, A4 was much darker than A3. Maybe a different upper limit to save battery in A4.

That is interesting, it could be.

Ok now we are talking. Gonna dig more info.

Congrats.
Did you get it already?
