I'm honestly expecting it to come out in 2015. Nintendo always delays their big titles [to polish them]
To be honest for me personally they are only a few things that will make me run to the shops and buy a WiiU.
1.Smash
2.Metroid
3. 3D DK (DK64 Sequal)
4. Proper 3D Mario...(like Super Mario 64 & Sunshine)
5.Diddy Kong Racing WiiU ( and it looks bloody damn good with Banjo & Conker back etc.)
To me it doesnt seem like any of these things are coming...or will come before smash..so im not bothered..plus my last option #5 xD yh impossible its a dream...
These are the only things that would make me run to the shop instantly as much as i want Wind Waker HD & Super Metroid because i have never played em before..i can live/wait without em..and Mario Kart 8 will be extremely tempting as it comes closer but i can wait without that too...
Jusy last month i got Mario Kart 7 and im pretty borrd of it...got 3 star driving liscense...good game! Better than MK Wii in most ways but DS one was soooo good.
Plus Iwata said they are more WiiU games coming in the space of Now till Spring 2014 that havent been annnounced yet because he said he doesnt want people to wait that long from time of announcement till release thats why he didnt announce them at E3..i doubt it will be anything special...well thats my take on WiiU.
Hope it gets a price drop at Xmas then i might pick it up this year.
