I'm pretty sure that was Metroid Prime Trilogy they were refering too :P They said it was good to get new people into the franchise (3 games for the price of one), ok for fans (as they already own the games but it was cool none the less to have a trilogy), I don't see how DK fits in apart from their choice of cover up sounds.. Also I'm sure they've used those monkey sound effects before..
edited to show my opinion more clearly
