Canon T2i to Nikon D3S?

I currently have the Canon T2i and the kit lens. But my birthday is in April and I was wondering if I should save up and trade-in the T2i and get a D3S. From what I've heard, the 1D mark II isn't that great and the D3S is much better. What do you think? And what should I do about lenses until then?

Added (1). Actually, I would be paying for the camera(notice how I said I would have to save up for it) and I don't shoot in automatic modes. I usually shoot in aperture priority mode to get the best depth of field effect.

Unless you need to shoot in the dark where your subject is illuminated by moonlight, stay with the t2i. If you absolutely need to shoot in the dark then you could go with the d3s. The lenses are as important. Since you've only got a kit lens, the switch wouldn't be that large. If you have the budget, go for two fast prime lenses such as a 28mm and a 50mm and you'll think more about composition instead of being lazy and zooming. It should also be much cheaper than a zoom lens. I'd think that if you're getting a d3s, your budget would be large and your skill would be high.

D3S is the best camera out there. Slap a 24-70 on it and you'd have a dream combination.

Question is, are you good enough to handle that camera? If your T2 is still in scene mode, if you use matrix metering because you didn't know there's other ways to meter, if the word meter makes you look puzzled then no, the D3s is not for you.

Your parents must be really generous.

You should consider that both D3 and 1D are big, heavy hulks of cameras. Lugging them around wouldn't be fun.
If you have a ton of money to spend and want to go full frame, why not a D700 or 5D and a excellent lens on top of that? The image quality is none short of the D3 or 1D, but they're lighter and cheaper. All you lose are some features that you likely don't need anyway.

But as the others said, odds are that you're just wasting your/your parent's money.
