Maybe Japaneses are not that much concerned with christmas as we are? Or simply the new product is the 645D and this kind of product is not affected by christmas sales.
Yeah it always make sense to ignore 33% of your potential customers.

That sent me running to the online dictionary, LOL. I'll take door B or C.
I hope I spelled it right - spelling is one of my (many) failings. Just ask my wife.

My wish, if there is indeed a GPS option is to have it in the grip. I don't see a GPS taking much space, I have one in my tiny Blackberry.
So does my cheap cell phone. The issue would be what is the ground resolution of an integrated unit as well as its reliability. If it is no better than a unit in a cell phone, blackberry or the ones Nikon are using, it better not add to the cost.

GPS when not as good as real good seperate receivers will always be less reliable but 100 meters isn't acceptable to me indeed.

That said, if only 3 satellites on the sky, there's no wonder, ever ...
Its good to see someone with an understanding of gps equipment post in one these threads that are discussing a potential K20d GPS model. I need a gps unit just to keep up with the gps threads!

I understand that cell phone type GPS units use an assisted GPS system. They increase their acuracy by triangulating with cell phone towers in the network.

If the cell phone does not have a clear line of sight to the sky, then they use distancs to the cell transmition towers to determine your location.

I think this is how they are able to produce such small GPS units in cell phones.

Does anyone know if a cell phone can be used as a GPS when it is outside of available coverage?

Some cell phones actually do have GPS chips inside but they cost a lot more than the AGPS ones.
The AGPS ones need the cell towers.

I also agree w/ the comments about 100meters vs. 10m. If they can get normal real GPS accuracy, it wouldn't be a bad feature, though my guess is it'll be an add-on. I think the Nikon one is $200...

No, it's not a P&S and it shows the future of Pentax... in a way.
It definitely fall in line with their new tagline - BE INTERESTING

Perhaps the nikon claims are buffered by the fact that the govt. can alter the accuracy of all GPS in order to avert perceived threats. If you read your GPS manual, it will discuss this innaccuracy issue--I've had the displeasure of reading nearly a dozen different GPS manuals (three different manufacturers) as well as the earlier Loran C manuals with similar disclaimers regarding accuracy. Without looking it up, I believe it is called differential GPS when the govt. plays with the signals. Govt. testing with the differential was relatively common during the Loran C days...I've had my location change while boating many times. Sometimes it switches right back to the original tracking, sometimes not. Now that so many people use GPS for auto navigating, there is less "testing" with the signal. But no company claims reliable 10 meter accuracy due to the differential GPS tinkering that can happen at any time.

Not sure why anyone would need closer accuracy for photo tags. If you can't recognize the location from 100 meters away, it probably wasn't that impressive to start with?

When you are trying to find a spring feed in the Wacissa River 100+ meters is a big deal. I can get 3 to 5 meters out of my Garmin mapping unit WAAS in North America. I just got 8 meters in the yard with only 4 satellites with my old Garmin V. Sure the DoD can turn on the SA and then they are next to worthless. This has been discussed in a couple of other threads where the GPS thing is being discussed. Some people use GPS for work related stuff.

Maybe it'll be a K20 with an M42 mount. Then those of us with a collection of them will be sitting pretty as the prices for 'old glass' go through the roof.

Heard there'd be a new one announced this Tue or Wed, but definitely not a K20D w/ GPS ... probably something for entry level again ... or an entry level camera in some silver or funny color? Don't think Pentax can make another new camera in such a short time.

The whole point of a DSLR is responsiveness. How does GPS figure into that? I turn on my camera and it's on in 0.2s, then I sit down and wait a minute for the GPS to lock onto satellites before snapping a few pictures and moving on? And why exactly do I want GPS coordinates of where I took my pictures anyway? Seems like an utterly useless feature.

Hopefully Pentax will announce a DLSR with a bigger sensor (APS-H or maybe even FF) or maybe a APS-C sensor with 3 stops ISO advantage over existing sensors.

New pentax path?

"showing the future of Pentax"
"INTERESTING"

... it sound to me like some kind of new concept or corporate policies are to be shown.

Will Pentax redefine its SLR design or key components(I am thinking on EVIL...)?
Will Pentax actively cooperate with another camera manufacturers ?
Is there any corporate merging in sight ?
