Switch Nikon to Canon? But I have so much equipment already?

I've noticed more and more people are moving from Nikon to Canon. I'm really into portrait photography and filmmaking as well. Canon has came out with a lot of new stuff. I heard Nikon is coming out with some new cameras this year, but they've only come out with the D800 so far. I kind of want to make the switch, but I already have a bunch of Nikon equipment! I have 3 lenses, and a flash and of course my camera. It would be so hard to sell all of it! What should I do?

Added (1). I just went to the NAB show convention in Las Vegas, and Canon had a giant set up with all of their new products and the 5D

You have noticed that have you?

I shoot professionally and in that arena, the tide is going from Canon to Nikon, manly because of the superior low light performance of the cameras.,

Take a look at how the sensors of both cameras compare. You will notice that most of the high performing cameras are Nikon's

Actually the Nikon D800, D4 and D3200 are out right now with more to come

Jumping from one brand to another is very expensive and should NOT be done just because others seem to be doing it.

There's a reason why Nikon dSLR sales have increased and Canon's has decreased in the past few years. Together they account for over 70% of all dSLR camera sales, but you really need to do more research and NOT be swayed because less informed people are doing it.

The Nikon D800 is the highest rated DSLR out there. If you look at the top cameras they are Nikons. You'd be crazy to switch.

Canon has not come out with a lot of new stuff, if anything at the moment it is seriously lagging. Sure it has some interesting patents, and a couple of new technologies have appeared on it's video cameras, but it is distinctly lagging behind the field at the moment.

What would you expect to gain from such a switch? After all, the camera is a tool, the most important piece of equipment sit's inside the head of the photographer.

As seen at
http://www.cameralabs.com/reviews/Canon_EOS_5D_Mark_III/Canon_5D3_vs_Nikon_D800_noise.shtml
Cameralabs compared the Canon 5D Mk III with the Nikon D800. Below ISO 800 the Nikon captures better detail. Above ISO noise intrudes more on the Nikon. For a portrait studio the Nikon D800 has the advantage, but for sports and wildlife the Canon 5D Mk III looks like it has the advantage.

Here is an article comparing the video
http://www.dslrnewsshooter.com/2012/04/01/video-shootout-nikon-d800-vs-canon-5d-mkiii/
Conclusion is mixed, with Nikon scoring a little better in detail in good light, while the Canon had less moire and low light noise.

I can't see why anyone would.

Half the world's pros use Canon, the other half Nikon, you couldn't pay any one of them to switch.

The big secret is… There's nothing wrong with either of them and changing systems is a waste of money. If you can do it with a Canon, you can do it with a Nikon - and if you can't do it, neither will do it for you.

I second the motion that changing brands will not improve your work. Cameras are cameras, measurebaiting over which one is 1/10% better at something is a waste of time. There are no bad DSLR's, just bad shooters. In my work and personal use, I use Canon, Nikon, Fuji, and Sony DSLR bodies. At the end of the day, you can't tell which camera was used for what photos. Video is different, because only the Canon I use has video, so it wins by default.

The gear you use is not important. Results are important. If the gear you have can get the job done, there's no need to change. Changing from one brand to another at equal levels will not provide any real change is the results you get. Changing from a Nikon D40 to a Canon 5DMkII will change your results, but not any more than moving to a D800 and not having to buy all new lenses and accessories in the process.
