When a dpreview forum member contacted Nikon Europe and asked them about the new D7100 being described as the “new flagship of Nikon’s DX-format HD-SLR lineup” on Nikon USA website and on the other hand Nikon D7100 is described as “enthusiast-level DX format camera” in Europe website, now take a look at Nikon answer to this question
“I can assure you that the D7100 is not positioned to replace the D300s as Nikon’s flagship DX-format camera – such is the information received from Nikon Japan on the matter.”

Nikon D7100 is not a true replacement of Nikon D300s, according to Nikon USA website. So for sure there is a room for Nikon D400 + the Nikon pro DX (300/300s) users are not happy about the D7100 buffer size / continuous shooting speed and they want a better camera –> Nikon D400.
