Question regarding Resident Evil 5 Co-op play!

For resident evil 5 co-op play, when playing online with your friend, are cutscenes going to change such as if you playing single player, will you get the same storyline  and cutscenes as you do in
co-op? will they take some out for co-op and change some parts of the story? will you go the same route as you do in single player if you are playing as chris? (or even sheva). will they have the same boss fights, enemys, minibosses etc.? thanks!

Who knows, but I hope it's not too 'bolted on'...
