When I first heard that there was going to be a Nikon D3200, the first thing that I was contemplating was whether it will also be another megapixels packed sensor camera like the D800. So the 24.2 megapixels sensor of the Nikon D3200 was really something to be expected even if it seemed a bit high. I had money between 18-20 but at least I didn't bet on it being the same as the Nikon D800. Mind you, this IS an APS-C sized DX format sensor so it's really plenty.
As an user of previous series, I recommend this upgrade for those still use the old series of D3xxx from Nikon. A huge improvement in megapixels from 10.2 to 24.2 will increase the creativity.
My experiences using D3000: I get the easiest way to create my state of art in photography. With this new series I get my skill upgraded significantly. So you better buy this and start to take pictures.
