Come on, it's the same thing every time a book (or anything) is adapted into a movie or has sequels or whatever! Everybody is making a scene of it! (I remember giant trolls about P. Jackson's LoTR...)
The *original* books of Asimov won't disappear anyway! The additional fiction won't make it change. The upcoming book might be enjoyable, faithful to Asimov, or not. And what if they don't? Will that change the face of the earth? Will that change the vision of Asimov's work in you heart? Nobody force you to read them, and nobody says "now, that's the official truth, robots are made of cheese and actually work for R. What Ismyname, the super demonic robot from oblivion. Just discard everything you knew about robots"
If you're not happy with what is added to the original work that you enjoy, just ignore it!
Last week I was at the Surrogates movie premiere in Paris, and the two authors of the graphic novel where there to answer questions from the audience. When asked if they were happy about the adaptation, they answered that they did enjoy it (well, that's what they say in public :P but that's not the matter here) and they said that whatever could happen with the movie, their own work wouldn't be altered, since it follows its own path, it was there before the movie.
