Dream List:
Mario Kart 8 in April
SSBU in May
SSB3DS in Fall for second wind of Smash U sales
X in Fall 2014
Yoshi's Yarn Holiday 2014
Zelda Wii U Holiday 2014
Boom.
Even though it hasn't even been announced, I also feel that Pokemon Something game will be for the Wii U and come out in late 2014.
EDIT:
Yeah, it makes a lot of sense for 3DS Smash to come out a lot later than Wii U smash. 3DS Smash will sell like crazy no matter what. Wii U Smash could be affected by 3DS Smash so it's best to release it earlier.
