Nikon D300s/D7000 fusion
One of the possible scenarios is that in 2013 Nikon will merge the D7000 and D300s product lines. There is a good chance that only one high end DX DSLR camera will be announced (D400 or D8000?) that will replace both D7000 and D300s models. The camera will have a "pro" body similar to the D300s and most likely come with a 24MP sensor and 8fps. The D3200 and D5200 should be sufficient to cover the entry level needs. The new DX camera will be the "transition model" to the full frame category (D600). Expected announcement: January/February 2013.
