Nikon D90 Coming in Early September? Or is it the D3X? Or BOTH??S

Nikon has been sending out press invites for an event on September 3rd. What could they possibly want to talk about just a few weeks before Germany's Photokina expo? It could be Nikon's sequel to their D80, the D90. Or, it could be the 24.4-megapixel D3x that was spotted in Nikon firmware. Or, in a slight breach of etiquette, Nikon could skip the D90 and just release the D100, making the entire photography world crap itself. Because that would be a photo op.
