Personally I wouldn't be opposed to taking "under God" out of the pledge simply on an argument of "let's be inclusive" or "let's not offend anyone", but if that does happen it should be a free choice, not something forced by the courts. If people want to remove it they should petition their Congressmen to change it rather than running to the courts.

I certainly don't think having it in the pledge is a breach of First Amendment rights. The First Amendment was put there to keep the government from establishing an official state religion like the Church of England and I don't see that having "under God" in the pledge does that. And even if one doesn't believe in a "God", nobody's forcing them to say those two words in the pledge, there's no reason they can't stand there with everyone else and just say "one nation......... indivisible, with liberty and justice for all".

Any court decision declaring it unconstitutional would, I believe, be a bad one. There's no Constitutional right to not be offended. I will however fully hold open the possibility of a reasoned debate leading to the conclusion that lawmakers should take it out.
