I do not understand why some people feel you must have full frame to do landscapes. When I first became series about photography, it was with wildlife in mind. I started with a Rebel XT, but right away wish I would have gone for the 30D. It did not take long though before I enjoyed shooting landscapes as well. Pretty much all of the photo's on my site are from the Rebel XT, 40D, and some from a rented 50D and 7D.
The major difference with full frame is basically lower noise (which it seems the 7DMII comes pretty close to catching up) and field of view. I can only recall maybe 2 times that I could not go wide enough with my crop camera and my 15-85mm lens. If I had a 10-Xmm or 11-Xmm lens, I would have been fine. It is a matter of understanding the differences, and getting the lenses that help make up for that difference.
Crop camera bodies can still take excellent landscapes, they are not just for wildlife. If you are 50/50 on what you like to shoot, I think you could go either way. If you are more into landscapes, then full frame may be the better option. If you are more into wildlife, then I would recommend crop.
If money does not matter, then just get the best in the 1D series!
