Exactly.
It's why I said Lucina's revelation was a gateway for Sakurai to justify the rest of the clones he put into the game. Once we accepted that it's okay to have a 99% Marth clone in the game, we weren't liable to bat an eyelash at Dr. Mario or Dark Pit. It's why the guy uses Robin's inclusion and Captain Falcon's return to distraction from Lucina's revelation. Seriously, the trailer starts, five seconds later, 'Lucina's in, guys!'.
Then not even two seconds later, 'CAPTAIN FALCON'S BACK YYYYYYYYYYYYYYYYYYYYEEEEEEEEEEEEAAAAAAAAAAAAAAHHHHHHHHHHHHHHH LOOK HOW AWESOME HE IS.'
Then not even ten seconds later, 'HOLY CRAP WHO'D HAVE EXPECTED ROBIN TO JOIN THE BATTLE THIS IS AMAZING!'
Gotta admit, the guy's smart. Either that or someone in marketing took a look at Lucina, cringed and said, 'There's got to be a way to soften this blow.'.
