Ergonomics something like this:

I really, really, really wish for the Implementation of 3 extra modes:

A Sonic emofeedback camera will recognise your state of mind and when shooting stills or right after pausing the recording of a shot will immediately feedback you with sound and phrases; with (at least) 4k options, i.e.

• EGOTRIPPING - fart sound / 2 Hrs of Philip Blooms advices on any other camera / very laud scream of contempt / etc.
• 50/50 - It's OK seen worst / Keep it as a hobby / sweet mother of jesus, have you seen that ass? / etc.
• SUICIDAL - Oh God, oh God, oh God / You're the man!! / fssshh you're on fire baby!! / etc.
• =(&%$¢∞@£‰¶£∞⁄•{‡ø9u÷{∏/&∞5!!!! Non stop ramdom Tourette mambojambo swearing

A Universe dematerialisation button, obviously with a warning message "Did you save your clips and close your zipper? This option is not undoable... as universe as we know it will no longer exist!"

An Alcoholometer with (at least) 4k submenus, examples

• no point in lying to me, I already know
• no point in telling me the truth, I'm driving anyway
• no point in telling me anything, I'm fucking this bitch (polizei)
• your dragon breath has activated Universe dematerialisation option, thank you for using Pana(fart sound)sonic products

@GeoffreyKenner If I were shooting Upstream Color 2: Electric Boogaloo, I would shoot it in 4K. It would yield a really cripsp 2K image.

This is a wish list, and not a "technically feasible" list, but here's what I'd like to have: a camera that creates both a 4K file and a 1920x1080 file of each take.

Why? I can't afford a computer that can edit 4K video. So, why not let me have a file I can edit? And when I do need a 4K master, I'd have my old footage ready to use.

In the meantime, I guess I could simply create 1920x1080 versions of the 4K files, and edit those. But this'd make it worthwhile to buy the camera now, and upgrade the computer later (instead of having to do it all at once).

5 axis inbody image stabilizer would be perfect.... But 422, better evf and 120fps@hd as @nobbystalus states is essential.

422 10 bit, better EVF, up to 120fps in HD. Not much to ask.

I think that in the request for this wish-list, less something very important: a better SEALING !!!! Is not acceptable that the flash trap and the SD Card trap don't have any protections !!!

I don't even care if they suck another life cycle out of the gh2 sensor, just make a body that can handle a proper cine lens without flexing all over the place. live hdmi out, 4:2:2 8bit is fine for my needs, If I want 10 bit, im going with sony anyways, they seem to get the big picture. AND FOR GOD SAKE, PLEASEEEE, PLEASEEEE, FIX THE F---ING COLOR SHIFT WHEN THE RECORD BUTTON IS PRESSED, my 1999 Panasonic pvdv710, didn't have a color shift, why in gods name in 2014 we cant get the same picture after we press record !!!!!! It might help to know what were going to get after we press record. How in their wacky mind it was ok to release a camera that changes what the image looks like after record is pressed. dahhhhh

Ok I'll bite. I'd really love a custom sensor-windowing function. For example , a sensor window for s16, for reg 16, for s8. And then a custom setting where the profile could be set by the user. Get to work programmers ! And ....all of the above !

I'm dreaming of 10bit 422, a broadcast ready 50mbps codec like the canon xf305, with a 4k upgrade at some time in the future. It would be nice if the body only was under a grand gbp

422 color sampling and 4 channel audio! maybe over aes/ebu or combined minijack plus the additional xlr plugs.

My wish: 4K, H265, under a grand.

@inqb8tr

Thank you very much. That is very important and relevant thing considering this topic. Are you disapointed if it still somehow will be GH4k. There are in Japan Playstation 4, Grand turismo 4, Nikon D4...

Have you nothing to say about my long reply explaining to you what you wondered? How polite is that?
