I don't believe there's any vegetable protein-based replacement that will taste as good or have the same texture as actual meat. I'd say people should be prepared for disappointing results.
As a vegetarian I try a lot of these kinds of things from time to time. I agree the 'chicken' has a way to go, but I think it is a bit short-sighted to say they can never be as good as the real thing to a meat-lover. I think you will be surprised as this technology continues to develop.
Having said that, most vegans and at least some vegetarians are not really looking for convincing meat substitutes. Some of us actually don't like the taste of meat.
