Well, 25 years ago, CCD's were specialists expensive sensors, not suitable for consumer camera's of course...

BSI sensors simply have a better quantum efficiency, and if they find a way to make them as cost effective as traditional sensors, they will come to DSLR's also.
Reading all those posts complaining about high ISO noise etc. makes clear that every little bit improvement will be welcome.
I never suggested they don't have better efficiency. Question is, when does one reach the point of diminishing returns?

For extremely small pixel sizes, BSI sensors offer a much greater potential advantage than they do for larger pixel sizes. Pulling numbers out of thin air, one might be willing to pay rather more to gain a 10% advantage than one would be to gain a 0.1% advantage.

That is why you won't see BSI in DSLRs any time soon. The slight advantage offered for a relatively large photodiode is outweighed by the disadvantages in other areas (cost / manufacturing efficiency, reliability, etc.)

Hey Ogl,

Here's the rumor on Let's Go Digital:

Sony Alpha A750

and at Photo Rumors:

http://photorumors.com/2009/10/30/sony-alpha-a750-leaked/

The Sony sensor sounds pretty nice, at 14 million megapixel the pixel size will be about 7.8 to 7.9 μm. At that size the Sony sensor should be able to handle high ISO and have low noise. Nikon is supposedly preparing to use this sensor in an upcoming camera also.

The price sounds great too, about $1500 - $1800. I really hope Pentax brings out a FF DSLR in 2010, I don't want to wait until 2011.

Yes. 2010. The price will be lower than $1800.
