On the pricing front, it looks like there is a new piece of information on the B&H Photo NX10 listing which has a price of $700: The five-item bullet list now includes an "18-55mm" entry. This is a preliminary listing though (you cannot pre-order it yet), so it may not be the opening price. But if we assume that this is indeed the opening kit price, it would certainly be a very competitive price, as it is about $40 more than the Olympus E-P1 zoom kit, $200 below the Panasonic GF1 kits, and $400 less than the E-P2 kits.
Speaking of M43rds, here is one discussion thread at the GetDPI forums talking NX-series from the perspective of 43rds users.
