Mmm, yea, I saw that.
I think it is logical to assume he means "more powerful than PS3/60." However, there's a chance he might just have been saying "the game will be good because WiiU *shudder* is more powerful than Wii."
EDIT: I'm listening to this podcast right now, I don't flappin' care if Kirby Wii is "breaking new ground" or anything. I only have one 4-player co-op platformer (NSMBWii... were there others??) and all I know is every time people played it there were tears of laughter. I can not WAIT for another such experience with one of my favorite other Nintendo characters, Kirby.
My wife has already called dibs on Kirby but that's ok cuz I'm psyched to play as MetaKinight!!!
