Then again who knows, Kirby got a new Final Smash so maybe other characters will too, or even better, with the customization options maybe characters will get multiple Final Smashes.

Still doesn't deconfirm it! We got a lot more Kirby Games in the time between now and Brawl, and Metaknight had a good part in most of them. Metaknight is OBVIOUSLY being Nerfed, so they might replace his standard b. If that's the case, he might use the Screen Clearing version of the mach tornado that we all know and love, or it could be something new, like Summoning Dark Metaknight from the amazing mirror for a double team combo. Don't give up hope just yet…
