Actually I think it'd be 52 or 54MP.
Bring it on, Pentax!

After using a Sony RX-100 for a while as a point-and-shoot, I am starting to like lots of [reasonable quality] megapickles. The extra cropping potential alone certainly comes in handy, and as DxO notes, extra megapixels can indeed help you disguise pixel noise.

What is most important to you.. MP or ISO? I personally like having higher ISO and think Pentax should stay with a 16MP sensor. Unless they can somehow keep a high ISO at 24MP???

Is there any chance that Svitek is trolling us...

I think we have agreed on that ogl. The other thread was closed as a result. Now let's move on from this and talk about what the K-3 will *really* be like. 24Mp APS-C is much more plausible that a 24Mp FF, but let's just wait for April to come along and reveal all.

It seems to me, K-3 is APS-C camera and
24-120/4 is DA16-80/4 in reality....I'd like to be wrong.

Svitek said that 24-120 is like 18-135 optically.

They will [hopefully] have to do better than that. Those soft edges...FF would just amplify that 18-135 problem.
Disclaimer: I have the 18-135 and think it is quite usable IRL. But optically it is not at all as good as my older SMC A 35-105/3.5 - that's the direction Pentax needs to go.

Judging from the Nikon D7100, maybe yes.
But high MP can balance out slightly noisy high ISO, especially when doing real-world stuff like printing images.

That's why I think keeping the pixel density of the k-5 for great high iso performance, and increasing sensor size to APS-H to get 24MP and the resolution it will bring will be the best of all worlds.

The new generation of 24MP has equivalent noise to the 16MP, assuming you post-process.
If history is a guide, Pentax would be using the same sensor as that 'new generation', just a year later than everyone else.

The K-5 was announced pretty much simultaneously with the D7000, and less than a month away from A580 and A55.

Perhaps, but (from my experience) that was
  1. a near exceptional lens as a relatively consumer-oriented ZOOM went, and
  2. exceptionally heavy as a result of all the glass that made it 1.
I'd be happy if Pentax could do that again but it would probably require a lens design breakthrough. Otherwise it might not actually be all that well received in the modern world. Technically, turning enough glass under the current autofocus demands might be a real technical challenge.

I'm sorry - I didn't mean that history has always shown that Pentax gets a sensor a year after everyone else.

I meant that history has shown that Pentax uses the same sensor as someone else.

In this case it could be a year (give or take) after someone else, depending on which sensor we're talking about... but no sensor is 'new'.

But the Sony A-mount is just the old Minolta AF mount, right? Like the K-mount, designed to cover 35mm film. Or don't Minolta AF lenses work with SR on a Sony SLR?

Please regard this question:
Why is the image circle of Sony's FF A-mount lenses larger then the FF image circle?

Answer:
To accomodate the sensor movement of the large FF sensor. That is exactly the same reason why DA lenses have an image circle larger then the required APS-C image circle.

But even that is not necessarily true. At some point - and you know it very well - they used a Samsung sensor.

In other words, the history has shown Pentax can either use a sensor one year later that their competitors, a sensor simultaneously with their competitors, or a different sensor.
However, for the next K-mount cameras I doubt they'll use a different sensor.

Based upon my views of the studio comparison shots on dpreview, and comparing k5 to d7100 to d600, it seems that the k-5 sony sensor has better high ISO performance than the 24MP toshiba sensor in the d7100,
