You know what is interesting? If one fell swoop, Sony has now redefined the P&S market with the RD-1. The ability to put an APS-C sensor into a P&S camera has now altered the expectations of other cameras in this category.
I agree that it seems a bit unnecessary to mention a seven-blade design and bokeh when the real-world lens is just 5.9mm.
Also, packing 8MP into that small sensor -- I don't know ... maybe they know how to deal with the noise better than other camera makers.
