This technology will be passed on to the new 7xx when it’s ready.
Here’s what a PROFESSIONAL thinks over at The Luminous Landscape.

I believe that the Sony A55 will also be seen as belonging to this pantheon. With its 16 Megapixel 1.5X sensor with clean high ISO capability and overall image quality goodness as its core, Sony then adds solid video capability with superior autofocus tracking, 10FPS shooting, greatly improved multi-point autofocus (though occasionally a bit flaky), a high quality electronic viewfinder, and an articulated high resolution LCD.
Add to this in-body stabilization that works with all lenses, all of Sony's current fancy shooting modes like sweep panorama, multi-shot HDR, six-frame-merging low light capability, and multi-frame noise reduction for shots up to ISO 25,600, and you have a solid (though small and light weight) picture taking machine, with as many gadgets and gizmos as anyone could want. The potential appeal of the A55 should therefore be obvious.
Oh yes, there are the 30+ Sony lenses available, not to mention the superb Alpha Zeiss lenses that leave little to ask for when it comes to optical and mechanical quality.
Did I mention that all of this comes in on the A55 at under $750?
The only real fly in the ointment is the currently crippled video mode that lacks manual settings for shutter speed and ISO. Also the camera will be of reduced interest to serious video producers without 24P mode. If Sony does, as they have indicated they might, provide manual video settings their sales will increase dramatically among those interested in video, and if they were to add 24P they'll have to beat videographers off with a stick.
The bottom line is that one can read all the specs, reviews, and test reports that one wishes, as well as all the chatter found on on-line forums. But the proof of the pudding is in the shooting (to mix a metaphor), so if the capabilities of the A55 appeal, my suggestion is to visit a dealer or a Sony store and check one out for yourself.
I think that time and the marketplace will show the A55 to have been a pivotal camera for Sony, as it brings a lot of new technologies to bear in a well specified and well priced camera.
I fully expect Sony to introduce much of what has been introduced with the A55 into higher specs models over the next couple of years.
The camera's EVF combined with its pellicle mirror will likely remain controversial until more people discover how much better it can be than the small and dim "window at the end of a tunnel" that most reduced-frame DSLRs currently offer. But, anyone coming from a full-frame camera, such as Sony's own A900, will find the view dimmer than they might prefer. The day of the all conquering EVF just isn't here yet, though these are getting better all the time.
There has been chatter on the forums about ghosting being seen on some images taken with the A55. This apparently caused by the use of a pellicle mirror.
I've seen the online examples, but have not seen any evidence of ghosting in any of the hundreds of frames that I have shot myself, including ones where I deliberately tried to make it happen. To the extent that there is such an issue, I regard it as quite minor and of the pixel peeping variety, and unlikely to be of issue to most photographers who aren't micro-examining their images at 200% on-screen.
