The most important introduction is the new ultra compact camera with interchangeable lenses. Sony never mentions the words "Micro Four Thirds" specifically, so we are left to assume that this camera (if it were real, of course) would not accept the same lenses as the Olympus and Panasonic Micro Four Thirds bodies do. The new model is still a concept at this point, but it's pretty clear that Sony wouldn't be pouring R&D dollars into a Micro Four Thirds alternative if it never planned on making this camera a reality at some point.
The other major announcement is a concept alpha DSLR, one that would reportedly replace the long-standing A700 model that currently resides in Sony's lineup. No real details were provided about this, but two prototype lenses were introduced alongside of it: a 500mm F4 pro lens and a 24mm lens that would be great for landscape shots. Hopefully Sony will take all of this from the concept stage to the retail shelf shortly; the Micro Four Thirds segment in particular is just now gaining steam, and there's hardly a better time to get noticed than right now.
New concept α products being shown include an ultra compact model with interchangeable lenses, additions to the α family (including a successor to the α700), along with new TX5 and H55 Cyber-shot® cameras, new printers and other accessories.
