Witcher 3? I got so bored with W2 that I stopped playing the mini-game driven story about six hours into it. If W3 is built around the same mechanic then I will give it a pass.
The Elder Scrolls Online : The new Old Republic. Minor failure that limps along but is not worth the hype. The downgrade in graphics alone will make it pale in comparison to Vanilla Oblivion. Compared to modded Oblivion, well it will just suck (like a hellgate).
Destiny had my interest until I saw the linear pathing to enclosed areas, HALO combat, and magic users in my FPS. Nope, gonna pass on that. Adding magic to HALO is not innovation, just an excuse for more particles.
Watch Dogs is the only real thing of real interest to me, and that is going to be muted by the over-hype that was Far Cry 3. I hope it is a good as Ubi-M keep claiming but will not count on it.
Last of Us is done by Naughty Dog, and has been released. I doubt they were trying to show teasers at E3 2013.
South Park: Stick of Truth is something to wait and get many, many reviews on first. Two words: Obsidian Entertainment. 'Nuff Said.
