I have only three
Beyond Good & Evil 2
Every time I hear about this game I get hyped. The first one is a classic. I have faith in ubisoft on this game, and Michael Ancel is a great developer. What I hope to see in the game is tons of side quests (with a handful of them involving rebuilding a town) and still having a similar feel to Zelda. As for how it is announced, just another teaser trailer similar to the one that was revealed at E3 ages ago,.
Sleeping Dogs: Triad Wars
Recently beat Sleeping Dogs again. It's a great game and a bit underrated in my opinion (being the best GTA clone I've seen so far.) I'm skeptical when it comes to Triad Wars. I really hope it doesn't turn out to be like Godfather 2 (where less time and effort was dedicated when compared to the first.) Despite this Square Enix have been consistently putting out great games (with the exception of their mobile games.) As for how it's announced I would like to see a trailer with gameplay, but also reveling the setting of the game.
GTA V Expansion DLC
Not much to say on this one. I hope it is similar to GTA IV DLC, and just adds a non-crazy story-line centered around the gangs in Los Santos. I really hoe they don't do zombies again and I'm not a fan of aliens either.
Costume Quest 2
Just got announced, enjoyed the first. Hopefully we will see some gameplay
A Square Enix Super Smash Bros
I really don't see why not. Although there has been no rumors or news on this, I'vee added it to the list. Square have a lot of franchises they could use, plus it's a mix of characters from Western and Japanes games (which Super Smash Bros lacks.) I would like to see; Adam Jensen, Wei Shen, Neku, Sora, Crono, Lara Croft, Kain (Legacy of Kain), a Thief representative, a couple of Final Fantasy reps, Dragon Quest rep, Hitman rep and more
