Luigi's Mansion needs to be remade for Wii U way more than Kid Icarus. Luigi's Mansion isn't designed to be a handheld experience, both in terms of game design (no checkpoints) and in terms of control design.
EDIT: I guess my E3 predictions will be
1. Rhythm Heaven Plus localized for 3DS, out Summer 2016
Yes
2. Pikmin 4 for Wii U, can be played on both NXes
Yes
3. The Legend of Zelda U can be played on handheld both NXes
Yes
4. Star Fox Zero delayed to NX, receiving major overhaul
No
5. Punch-Out!! 2 for NX launch
No
6. Metroid Prime 4 announced, playable on Wii U and NX (with major visual enhancements when played on NX)
If a new Metroid is to be developed it'll be NX only as stated by Prime director Tanabe
7. Undertale revealed for 3DS, Wii U, and NX
Wii U and 3DS don't support the engine Undertale was made on. NX for sure.
8. Mother 3 revealed for Wii U, renamed EarthBound 2, and released on Virtual Console as well as in the "EarthBound Collection" for Wii U and 3DS
Mother 3 will come, don't know if they'll mess with naming or make a collection
9. Paper Mario revealed for Wii U
90% sure this will happen
10. Super Smash Bros. for NX revealed, shows off 3DS content as well as Wolf, Paper Mario, and Dixie Kong
It'll come, but no dlc characters except for the scrapped Ice Climbers and the Inklings to market the popularity of Splatoon
11. Pokemon Z (or possibly a pair of games instead)
For sure
(outlandishness grows substantially from this point on)
12. Surprise Mario Kart 8 DLC announcements, introducing two final packs that include two guest characters (Kirby and Samus), two classics (Bowser Jr. and Diddy Kong), and two new ones (*shrug* Captain Syrup and Dixie Kong?)
13. Major collaboration between Nintendo and Capcom (Nintendo X Capcom as the next big multi-player Wii U game?)
Metroid Prime: Federation Forces receives huge overhaul - models made more realistic, single-player is more akin to a proper Metroid Prime game with a proper, defined main character (maybe even Anthony Higgs). Samus is integral, but not the star.
14. HUGE Mario Maker DLC expansion to be rolled out until the end of 2016, featuring new themes, enemies, power-ups, functions, amiibo costumes, environmental objects, water/lava tiles - all for free. Leading into this is then...
15. Mario Maker 2 announced for the NX. BC with Mario Maker levels, and has tons of new additions, including a story mode, a world map system taken from Super Mario World, and game modes for Super Mario Bros. 2, Super Mario World 2: Yoshi's Island, Super Mario Land, Super Mario Land 2: 6 Golden Coins, and their real big leap - Super Mario Galaxy, allowing for players to create 3D levels.
16. Nintendo announces that it has licensed Bomberman and will release a Bomberman game for 3DS, Wii U, and NX's eShops (with compatibility between all three).
17. Splatoon NX announced, featuring improvements to multi-player, but mostly focusing on improving local multi-player and creating a huge, robust single-player mode.
I hope I get at least a few right lol.
