The problem with calestenics is the lack of progressive overload. You eventually reach a point (not very long, either) where bodyweight only exercises don't provide enough resistance to see any sort of improvement.
True, you can increase your rep range, but when you go much beyond the 15-20 rep range, your working the muscle tissue more aerobically than anerobically. Although it certainly has its benefits, Aerobic exersise yields little improvement in actual muscle size or strength.
For real life examples, look at a sprinters legs (short 'sets', long rests) to a marathon runners legs (endurance training, longer 'sets'). You will NEVER see a marathon runner with large legs, as they are training aerobically, and the mucle simply will not grow when stimulated in this fashion (in fact, it typically shrinks as the type I muscle tissue attrophoies from lack of stimulation and a high level of cortizol)
But, to answer your question, yes, you will see an increase in stamina, a general 'hardening' of the muscle, to a point, and little if any increase in muscle size. As far as fat loss, that is more a factor of actual calories burned compared to caloric intake.
