This was published by BJP just few hours ago:
“As BJP went to press, Nikon unveiled two new digital SLRs – one entry level and another semi-pro – as well as new lenses. Both new DSLRs come with a high-definition video mode, with the entry-level model, the D5000, also offering a swivel LCD screen – a first for a Nikon camera.”
Is this a clue that the next Nikon semi-pro model (D400?) will have HD video?
