Why do people put so much hype on new cameras when they probably aren't even using their current camera to the limits.
Photography is completely different to other IT sectors; computers, graphics cards etc - An old camera will still take great photos, it doesn't suddenly become obsolete because a new camera is out
One of things Nikon/Sony need to work on is decreasing noise at higher ISO settings, it's clear to me that this new camera is not going to address that issue as it's using a similar sensor to the current Nikon D200 and Sony A100.
Better to wait for camera improvements that will actually improve the quality of your photos
