Forza 5 the car roster is still a big mystery and so is the track list and other features.

There are plenty, but if I have to pick just a few, I'd say Destiny, Halo 5, Sunset Overdrive, Quantum Break, and The Division.

I really want to know more about the next Zelda game.

The Order 1886, MGSV, The Division, Smash Bros. Wii U/3DS, Knack, Bayonetta 2.

there's a lot, but my 2 most anticipated ones are X and Zelda U

Where to begin....
Nintendo: Metroid (not Team Ninja), F-zero, Star Fox, Wave Race, Mario Kart, Pilotwings to start. If they brought a few of these out it would be enough for me to pick up a wii u.
XB1: Crackdown 3, The Division, Titanfall, Sunset Overdrive, and Dying Light.
PS4: Anything from Naughty Dog. I'm not a PS fan but Naughty Dog has won my heart. If Nuaghty Dog had like 5 more teams with the same level of creative and technical prowess, I'd get a PS4 as well:).

Wind waker, google it.:) j/k. I'd like to see the other one they have in development

Metal Gear Solid 5 and X

Kingdom Hearts III (more info about the gameplay and what worlds will appear)

AND Monolith Soft's game X, I want to know if it's related to Xenoblade or not, and I think the game looks too sci-fi for me, I want too see more places like the Eryth Sea and the Satorl Marsh.

Mass Effect 4, Kingdom Hearts 3, and Division
