There's no reason it could not be K-mount, every 35mm film body that's K-mount is proof that you would not need a new bigger mount and then adapt it.. this is not a MF sensor.
Originally posted by Aristophanes The smaller you want it with a bigger sensor, the larger the body. You want 10 FPS? Bigger body. 1080p video? Bigger body. Longer battery life? Bigger body. Dual SD card slots? Bigger body. WiFi/GPS? Bigger body. Fast AF? Bigger body. HDMI and USB out? Bigger body. FF SR? Bigger body. WR? Bigger body.
more FPS = Bigger body?? Really?? Please understand that the amount of transistors and I/O functions video card and CPU manufacturers are cramming into a small processor is becoming unfathomably large.. it's the processors ABILITY that determines this, and it's not always in line with its SIZE. Take a CPU on a cutting edge cellphone (android/Blackberry/iPhone) and then see the size of a solid state 2 or 4 GB module.. there is no real need for increase of size, heck it would probably be a DECREASE of size needed.
1080P Video = Bigger Body? ok come on now.. that's like saying.. you want more colors than 16 in your old monitor well I'm afraid it will be the size of your dishwasher... this is again, simply processor's ability.
Dual SDHC = bigger body, yes.. it's an actual physical port.. BUT they could be smarter about it and have it in the grip if they use the same camera body system as the K-7/5.. they have a spot to HOLD a card.. just make one to USE the card instead.
Wifi/GPS = Bigger Body.. possibly, again IMO this is something that could fit in the grip as well, there is a lot of wasted real estate in the grip.. so whether it's a one piece with grip or a separate grip it could be done either way. But it would also decrease battery life expectancy.
Faster AF = Same as others above, processor ability and light meters used.. it's possible it could take up more space, but considering the Nikon/Canon base model APS-C's are not really that large I can't see it adding size... still limited by the screw drive/SDM and DC motor systems, I hope they tweak this in this next generation for 2012!
HDMI/USB out = Why would it add when the K-5 already has this port?? Just purchase the proper cables and your good to go! No size addition needed from K-5!
FF SR = To move a bigger sensor, it will take some in camera real estate to mount the sensor on an SR pad, which in turn will have to have some space to move a touch.. so obviouseley it needs a bit more space, would be interested to see how much space is on the other side of my K-5's rear LCD as is.. But probably bigger size required.
WR = Bigger Body.. umm no.. putting in seals is not what makes the K-5/7 chassis as nice and beefy as it is.. it's the amazing full alloy body that add's a little size compared to cheap plastic.
I agree some items are hard to get around.. but for the most part, newer tech and good R&D can overcome a lot of adding bulk to the camera. If Pentax were to simply buy tech from a few years back to save cost, it would be doing a disservice to itself anyways by putting out a "sub-par-oversized-for-what-you-paid-for camera". I just can't see that ever being the case.
