There's a lot of factors that could influence which brand of DSLR you end up with. In my case, I picked Canon because I have friends around me who have healthy collections of EF lens (i.e. easier to get my hands on and try out different lenses).
If your friends are generous enough to let you borrow their Nikkor lenses, by all means get a Nikon body. However, if you have to rely on your own collection, then both would be valid options since you won't have the burden of existing lenses.
As for picking bodies, I would suggest waiting for three-to-six months before you invest on a newly released body. For one thing, the verdict would be pretty much set by that time - whether it's a classic or a bomb. Furthermore, the supply should be adequate and the price would have gone down a bit too. Unless you really have important events that you'd absolutely need a camera (you can also considering renting one if you don't want to make the choice yet), waiting for the dust to settle a bit would be a better choice.
PS: regarding so little heard about 60D, my guess would be either that not many people are buying the camera or that there's not much problems with it.
