I can see how someone would maybe think that, but it really isn't the case. Having some questions and doubts about the Firaxis Xcom is only natural because a) we know almost nothing about it, b) we've been burned before with mainstream attempts at reviving iconic franchises, c) the publisher's president went on record to say that "strategy games just aren't contemporary", d) it's a multiplatform game so there may be some amount of simplification in order to appeal to the mainstream.
I'm not wishing for it to be bad or anything, I would absolutely love it if both Xcom and Xenonauts turned out to be great, fun games. I'm just cautious and skeptical until we learn more about it. I was equally skeptical about Xenonauts at first because so many similar projects failed to capture the feeling of the original games, but now that I've played the alpha I know that it's shaping up beautifully. That's all. No hostility, no fanboyism, just the fact that we know much about one game and next to nothing about the other.
