Define Pro body...
What I mean is, why is there a perceived need for a label of 'pro' body?
Does the camera do what you need it to do, and produce images that are of the quality you require? If the answer is yes, then the camera is suitable for your purposes. It doesn't matter if its a 'pro' body or a 'pro' lens in its advertising. It is what you do with whatever you have that counts.
Only other photographer care what equipment you used, the rest of the world are just enjoying the images.
