I am pretty much seeing “let MT do all the work developing and we will pick the cheapest supplier that copies them pretty well” thing going on here. I am not knocking anybody personally, just the business practice, and it is business.
If I were MT this would suck, if I were trying to make the most money possible it would not. You get what you pay for. I have dealt with MT and their work was exceptional, creating the textures I designed for our products with minimal turn around time.
