I'll keep it brief, because we've already heard this news 20 times before due to the deliberate leaks at Sony: today Sony announced the 24mp A65, A77, and NEX 7 cameras, the NEX 5n update, the 16-50mm f/2.8 Alpha mount lens, 3 new E-Mount (NEX) lenses, and a host of other accessories. These items have various ship dates between now and the end of the year.
Of course, all the Nikon fan boys are jealous of the 24mp number and probably threatening to jump ship now, but the jump from 16 to 24mp isn't a very big linear increase.
