In case you missed it, Nikon announced an upgrade to their top product line. A new model, the D3s is coming soon. The camera looks to be a great upgrade, although for video lovers it's still using Motion JPEG compression (which is much grainier than H.264). The camera does over several other improvements that make it a nice upgrade.
Me? I'm still playing with my D300S and will have more to share on video mode soon.
