Only you can decide this. It depends on what you want out of a camera.
But, you should definitely NOT decide solely on the basis of one or two minor features on the latest camera models. When you buy an SLR, you are buying into a complete system and you need to consider everything: lenses, flash, accessories, etc., but most especially the lenses. Even if you are just starting out with a single lens, you will eventually want to add to that collection. (And surreptitiously sneak it into the house when your spouse isn't looking.
) Traditionally, Canon has held a slight price advantage over Nikon in lenses, but there are plenty of exceptions.
Technology is changing rapidly and camera bodies seem to be running on about a two-year cycle these days, so eventually you will replace the body itself but you won't want to have to start all over again with a lens system.
Read reviews as they come out and take EVERYTHING you read on this site with a grain of salt. No one here is objective and many of the discussions center around esoteric technical points that don't have much relevance to the average person. This site has a comment history, that will enable you to see what axe the commenter has to grind. There are also some very knowledgeable people contributing to this forum (folks that have far more technological knowledge than I do or care to have). You can identify them from the comment history as well.
Remember that anything you read here about the 60D is based on a camera that hasn't even been released. If you care about the technical details, watch sites like dpreview.com. In my opinion they do a very good job. Others may disagree. You can read the photography press as well, although you'll find that they tend to be advocates, rather than critics (don't want to offend the advertisers, you know.) Still their reviews are generally reasonable.
Ultimately, the camera is just a tool and you'll be able to take great pictures with either one.
