I reckon the reason they did this is cause they strongly feel there is nothing worong with the D90 footage. Its crisp, sharp high bitrate with smooth non-jello footage and simplistic auto features simply cannot be improved upon.
But seriously,
Sometimes these companies release a second similar model with subtle differences thinking it will cause the consumer to struggle between which nikon to buy, as opposed to which brandname to buy - canon or nikon. Manfrotto/bogen are notorius for this with their 50 million legs.
I mean a lower quality lcd screen that pivots. This is ridiculous.
