Well, in your OP you were actually asking for a reliable source, and with nothing except your last-ish post to also think there was a Fo4. Without said post, your point came out as "I don't think they're working on a FO4". That's why third post and first post contradict themselves.

As for the second question, yeah, I usually do that.
