Maybe nobody want's your stuff. I presume your current camera has P,A,S,M, ISO, and WB. What you appear to need, maybe, are better lenses, perhaps to do the sort of things you want to do. Now, having chosen Sony, you are really committing to buying mail order, because they will not have a widely available stock in the stores. For that, you should have chosen Nikon or Canon.

If it doesn't sell, I'd recommend you order yourself a nice lens and get to know the art of photography, and not worry so much about the silly differences in equipment. If it does sell, well, choose a system. I really don't care what, but choose it carefully. Take your time. Do your research. Then get a system that you can use for a long time.
