I have heard that a new kind of advance ccd sensor's will soon be available with great advantages. There will be no need for the use of primary filters in the camera (red green blue) so since each filter has a factor of +1 or +2 stops there will be no noise on high iso settings or at least up to 800 iso.
800 iso will give the quality of a 100 iso setting. No camera shake anymore plus more depth of field. Also cameras may have a lower setting like 25
for more flexibility. Does anyone knows about this issue or where I can find more info ?

Hmmm, haven't heard of that advance but a somewhat related technology was announced some time ago by Kodak (http://www.kodak.com/eknec/PageQuerier.jhtml?pq-path=2709&pq-locale=en_US&gpcid=0900688a80720f9d). They removed half of the RGB filters (the corresponding pixels will get full light) and proposed several patterns for the remaining filters.

Apparently, the new patterns work better with CMOS sensors than with CCD sensors... It seems that all P&S manufacturers will move to CMOS sensors in the not too distant future.

Might what you have heard be connected with this topic on FredMiranda.com?

The diagram is interesting.

Hello Laertiscy, and welcome to the Camera Labs forum!
You've already had some valuable feedback from forum-members. But still I'd like to give my two-pence too:
Unless you go for three sensors like in some pro camcorders, we will not be seeing brakethroughs in sensor sensitivity of a given size. The s/n-ratio is already at the physical limit and twiddling with the color-filters, leaving every second photo-cell uncovered, will yield not more than 1EV imho.
So don't expect miracles in s/n-ratio any more.
Sure the resolution will go up. But th eonly way to reduce noise today is: go for the biggest sensor that you can get!

Glad I could help!
Check their blog entry for the technology if you want more info (http://johncompton.1000nerds.kodak.com/default.asp?item=624876).
