The trolley cart in the Marth/MetaKnight video was straight out of Kirby Super Star's Great Cave Offensive game. I actually noticed the Kirby/SSB similarities back with Melee, all-star mode is pretty much the Arena from KSS and even uses music from KSS for the rest area.
It also looked like Kirby GCN was using the Melee engine.
