Like DeadlyxImpulse, I'd like to see a new unseen non-princess female character. (However, I guess you could argue Pauline would be new and isn't a princess.
), but I'd also like to see a new male human character as-well. This is extremely wishful; but according to Rosalina's storybook, she has a long-lost brother. Perhaps he could make a surprise debut?
Maybe not in this game though.
DK is a significant character, and I'm assuming Mario Party 3DS won't be as huge as Mario Party U, so it would only be right he should remain unplayable until his 'huge return' in Mario Party U. Diddy Kong is a possibility for Mario Party 3DS though (but not any other Kong).
Koopalings would never be playable, but there's a (small) possibility they could make an appearance in the Bowser style map.
