Few questions!
Can one dive for cover as a defense action, like parry or dodge? Or must one already be in cover to get the bonus?
Will being in cover effect use dodge or parry stats?
Will being in cover offer any disadvantages? And can one fire from cover unimpeded?
Can one use a delay action while aiming at cover to wait and fire at the opponent once they peek their head out?
Good questions, but some of the answers are in my original post. =)
1. Yes, if someone dodged (physically moved their character, Cyclone, mecha, skateboard, etc.) and if the cover were close enough, I can imagine allowing characters to "Dodge into Cover."
2. Being in Cover does not affect Dodge, Parry, or Roll.
3. Not in Light Cover, but Medium, Heavy, and Total offer Strike penalties (see original post).
4. That's called "Preparing an Action" and this assumes the character does poke their head out. If you're inside a World War II-style bunker or the like, you're literally in Heavy Cover. But if a character pokes their head out outside that cover for any reason, a character with a Prepared Action might possibly get a Strike on them with either less to no penalties. It depends on the situation. =)
