LCD monitor is better than Optical Viewfinder

Well,

High quality LCD monitor is better than optical viewfinder because:

1. Digital SLR shows the photo on the tiny LCD monitor AFTER the
shot but tiny compact cameras with huge LCD monitor show the photo
BEFORE the shot (D70 vs. Sony DSC-T3).

That's because SLRs actually use the "true" image being captured. TTL = Through The Lense. By the way I have both the D70 and T1.

2 The replacement of noisy mirror, heavy pentaprism and mechanical
shutter with the high quality LCD monitor makes the camera smaller
and lighter.

Actually its the lense that adds all the weight. The smaller CCD sizes on digicams allow it to use smaller lenses - less glass, less weight.

3. Good LCD shows exactly what you will get. For example, is the
photo too light or dark. Optical viewfinder shows something else.

Take a pic and display it on your digicam LCD while reading this post. Now walk outside in the sunlight - does it look the same? I think not...

Look through the optical viewfinder at a scene outdoors. Now walk outdoors and look at the same scene. It will look the same.

4. LCD eliminates the camera noise and vibration problems. Noise
freezes the peoples and scares away timid animals.

The LCD has nothing do do with noise. The noise come from the shutter box and mirror.

5. LCD enables much faster shutter and flash synchro speeds.

Again, this is a mechanical limitation. Digicams use electronic shutters and don't have physical entities move out of the way. DSLRs use a physical shutter curtain to keep light off the sensor.

6. Movable LCD is much more flexible to use than a mirror
viewfinder. You do not need to put your eye and head on the same
place as the camera.

Very true! One feature I love about the swivel bodies is that you can shoot waist level easily.

7. Much lower production costs -> more profits or cheaper cameras ?

Mirror SLR was a great invention when Ihagee introduced Exakta at
1936. However, nowadays a mirror is an old relic.

Not so. Try manual focusing using an LCD (even a really high quality one). It is very difficult to focus because the resolution isn't there. With SLRs the image through the viewfinder is exactly what will be recorded, but the recorded image will contain less detail than what you see. This makes focusing much easier.

Also LCDs typically have slow refresh rates, especially when light conditions are less than ideal. And it becomes next to impossible to frame subjects in nightscenes. With SLRs all this is easily done.

It basically comes down to:
DSLRs: view more image detail than will be captured
digicam: view less image detail than will be captured

Nikon, Canon, etc. compete fiercely with large sensor size SLR
cameras and with small sensor size point and shoot cameras. They do
not realize that some customers prefer long depth of field combined
with interchangeable lenses, speed, small size, and professional
price.

Actually, many advanced photographers prefer control over their DOF. Smaller sensor sizes hamper this control by making it difficult to use a shallow DOF when desired.

There are other benefits to using larger sensor sizes too. Is much like using APS film (or something like 110 film) vs. 35mm film. The larger imaging surface is going to yield higher quality captures.

Nobody has made a small camera with interchangeable lenses, small
sensor size and with large high quality LCD monitor without the
clumsy optical viewfinder, noisy mirror, heavy pentaprism and
mechanical shutter. For some reason there is no competition in this
field at all.

That's because its not feasible. You seem to be sugguesting a digicam with an interchangable lense system. This opens up the imager to the elements. Dust and stuff can get on the imaging sensor and require periodic cleaning, that if not done properly, can destroy the imaging device.

Additionally, add on lenses are offered for most high end digicams that increase the telephoto reach, widen the angle, or increase the macro of the built in lense. Many of these addons are of such high quality that no noticible image degradation results from their use.

Of course optical viewfinder and impressive, heavy and large camera
is good for some projects where you need respect and authority.
Many photographers also love traditional "Click" sound but this may
easily added as menu option to the noiseless camera.

Actually, its more precise than using the LCD. I don't care for the "click" sound, but its a fact of life for SLR users. Imaging being able to drive a car where the engine doesn't make a sound. Nice, but its not going to happen, so why worry about it.

What is good and what is bad depends on your needs. Boat is better
than car on water but the car is better on the land.

Yes, but you're arguments above sugguest otherwise.

My point is that I hope Nikon, Canon or Olympus will develope a
small professional camera with high quality LCD monitor,
interchangeable lenses, small sensor size and TTL flash.

They have. Check out the 8800 (Nikon), Pro-1 (Canon), or C8080 (Olympus). They have everything exactly like you are requesting.
