Although crudely put, I agree with Dudeman. There's no reason to sink $6000+ into the professional grade body when current offerings can be used for years to come at a fraction of the cost, unless you are certain you will be using the gear on a professional basis.
I dont get where this idea of 'if I dont buy the latest and greatest, whatever I have will be inadequate' comes from with camera gear, but it really needs to be quashed. You dont need to spend $6000 to have a quality camera on your hands; you can participate in the Canon Loyalty Program, send in a broken point and shoot and get a 7D for about $1100. This should be plenty of camera for most people, and will allow you to use both EF and EF-S lenses. While the body is a couple of years old, it's still arguably one of the strongest crop body cameras that Canon makes outside of the 1D series, and most of its limitations on noise handling, etc, can be rectified by capturing an ideal exposure.
Yeah, I know, I'm not the best example of this (I only minimally shoot paid jobs, etc) but I've also been shooting off and on for 10+ years, and photography is one of my primary hobbies (having stepped away from music). Just because you have the money to sink into it doesn't mean you should.
As others have indicated, get a decent quality body and invest in a couple of good quality lenses to start out (they dont even need to be L glass, some of the non-L lenses currently offered provide fantastic image quality at sometimes less than half the price). Learn with what you have, and then re-evaluate in a year or so if you want to pick up newer gear, etc. When you do this, ask yourself if not having a certain lens is holding you back (or if you feel that having a certain lens would help you out a great deal in the way that you shoot). That way, if you decide that it's too much of a pain to lug around a DSLR to everything you go to, then you're less invested and it's usually easier to sell less gear (especially not as expensive gear) than it is to sell high end gear (and lots of it). On top of that though, new offerings may affect a price change on the lenses you become interested in (either by way of people selling the old version for a loss to have funds to pick up the newer version, etc).
To add a little perspective -- let's say you wanted to play golf, and you're getting into it now. Are you going to go out and buy top of the line iron sets with a personalized driver, putter, shoes, etc, or are you going to pick up an entry level set for about 1/3 of the price but that's made by the same quality manufacturer? How about if you want to learn guitar, are you going to run out and spend $3500 on a Gibson hollow body guitar, or are you ok with an Epiphone Les Paul at about 15% of the cost? Yeah, arguably, the more expensive guitar is going to be better built, have a richer, deeper tone, etc, but it's still going to sound like crap until you learn, practice and master it. A higher price tag doesn't automatically make you sound like BB King; buying a 1Dx isn't going to turn you into Ansel Adams or Bob Martin..
(Just a note - I'm not trying to say 'zomg what are you talking about ur ridiculous' or say that it's merely the opinion of the OP; it's more of a discussion on how people fall into that trap. Not meant to attack obviously, just trying to help.)
