Rumor or reality: Nikon D400

On a Flickr group, I heard about a replacement of Nikon D300 (D400) to be announced on April 14, 2009.

Can this be true? Are DSLR makers this desparate to get half cooked models out at this rate? Canon has just announced a Rebel T1i which is virtually a Rebel XSi with a higher resolution sensor and a video mode.

Consumers are going to be mad with DLSR makers if the latter continue this trend. Many consumers actually wait for an year or so for prices for a new model to slide down before they can afford it. But if even newer models keep coming up once a year, everyone's investment on the most recent one just looks like a waste.. doesnt it?

Anyways, more models must mean previous models going on sale. So wise buyers will still go for a model or two back in the lineup and save their money for better glass (lenses) instead.
