Save up for the 5DIII. Heck, use a credit card and just get one. Big advantage is the wide angle. I have all the Canon wide zooms. It is as close to a professional camera as you can get. Accurate focus and you do everything on the LCD. It even has a HDR mode.
I am also considering the Sony A7r. 36 Mp. It has focus peaking which I enjoy for focusing via the viewfinder. Comes with a Metabones adapter so I can use my Canon glass.
You know 5d mkiii was JUST on sale before Xmas, it retails for $3500 in the US, it was going for $2600 USD on many sites in December. Then it went up to $2800 USD. Now it's back to full retail. Oh well.
I really don't need new gear, I have a great tripod and ballhead (Really Right Stuff carbon fiber with an Arca swiss head), I've got the top basic lenses - the 24-70mm f/2.8 II and the 70-200 f/2.8 IS II, plus the EF-S 10-22mm, a 50mm macro, a 100mm macro. I don't need more gear, I need more time taking shots.
I just got the Fuji X100s, it's so convenient, small and light, people look great color wise, I find I do almost no post processing as the color is just amazing from the get go. No lenses to fuddle with, just go and shoot. I'm not the photographer that you are, in the end I just got into it to take family photos.
But I do want to take scenic photos, I bought an expensive 1000x neutral density filter to take time lapse in bright light, haven't used it ONCE!!! That was the whole point of getting the tripod! Haven't use the tripod hardly at all.
