Sony has release 4 new cameras, 2 with the newest technology from Sony the SLT(Single Lens translucent) camera
What is SLT??
Sony's latest interchangeable lens cameras 'SLT' stands for single lens translucent and it's the 'translucent' bit that's the key to what differentiates these new models both from conventional DSLRs and mirrorless interchangeable lens cameras. The SLTs do have mirrors, but they're mirrors that let the majority of the light pass straight through to the sensor, rather than having to swing out of the way to allow exposure. As a result they are fixed in position, always reflecting a portion of the light emerging from the back of the lens onto a phase-detection AF array housed in the top of the camera. (A newly-developed 15-point array in the case of these two cameras).

'mainstream' DSLRs out for 10 yrs already, since the Canon D30 3 megapixel camera which cost ~S$5k back in 2000.
These SLTs I think will shake the industry up similar to what Canon 300D (sub USD1K camera), and the Nikon D300/D3 (real superb noise control up to ISO25600) did.
Sony seems to have a knack to introduce new features in their entry level DSLRs before moving them up to their other series.
