Hmm...could this be April Fools? Would a company pull off a stunt like that?
EDIT: I gave it a shot anyway. I went with "A Belmont (e.g. Simon, Trevor, Richter)"...I just want a whip wielder, I don't think I care who...though I did also say "NOT Lords of Shadow". I do have that preference.
I tried to be..."eloquent"...ish...perhaps thinking it might persuade them to actually do it, if this is for real.
"Castlevania, and the Belmont legacy, has been enjoyed on many of Nintendo's systems for over 25 years. Much to the chagrin of fans, the series hasn't received much love recently, despite an attempted reboot (which seemed to be disliked by many fans.) Given Castlevania's rich history, a Belmont could easily fit into the Smash Bros. universe. The whip would be a great basic weapon (like Link's sword) with a plethora of sub-weapons and powers to add to the character's move-set. Also, other features of the series could contribute towards items, levels, assist trophies, other characters, and more!"
