http://gonintendo.com/?p=2958*RUMOR* Sakurai announces three new Smash Bros. Brawl characters
June 7th, 2006
While there isn’t an official confirmation, I would expect this one to be true. Sakurai, Smash Bros. Brawl director let three new characters slip via a Japanese radio show. And the winners are…
Get ready to shed a tear for Mr. Game & Watch, Young Link, and the Ice Climbers…as a return for these characters doesn’t look like it will be happening. On top of that, it seems that the final number of fighters will be somewhere around 40, so there is plenty of room for brand new entries.
Reader Juno Reactor is calling bull on this story, staying that it stemmed from a fake poster on Neo-Gaf. While there hasn’t been a confirmation of the story, keep a watchful eye out.
so take it as u will
