I won't. I'd love to have classic Melee stages such as Fountain of Dreams and Fourside as DLC. Especially if we see them in glorious HD on the Wii U version! But of course I'd also like a few new stages.
A prediction on Nintendo DLC based on mario and hyrule warriors and fire emblem DLC
The blank pack
1-3 characters (likely to be one original and a clone)
3-5 stages.
5-10 Mii fighter costume pieces
The unknown pack
1-3 characters
3-5 stages
5-10 Mii Fighter costume pieces
1-3 alternate costumes for other characters
The little more money pack
1-3 characters
3-5 stages
5-10 Mii Fighter Pieces
5-15 Trophies
One Game Mode.
The You bought them all, have a bonus pack:
That one character you actually wanted as an alternate costume or Lucina/Luigi like clone. Either Ridley over Charizard, Vaati over Ness, Geno over Villager, K. Rool over Bowser, Dixie over Diddy, Wolf/Krystal over Fox, Bandanna Dee over Meta Knight, whatever. The game is going to read your mind and figure out exactly which character will mess with your head the most if they do it as an afterthought as a DLC collector's bonus. And that's who you're getting.
And a really really cool stage. Like Mushroomy Kingdom for the original Bowser's Castle.
