LOS ANGELES — Nintendo's Wii U and Sony's PlayStation Vita made headlines at this year's E3 Expo. But aside from those big hardware reveals, surprisingly few unexpected videogames were unveiled.

Instead, publishers mostly opted to take attendees at the annual videogame industry trade show on a deeper dive into previously announced games and their features. That's where some serious revelations were made.
Here are Wired.com's takes on the big announcements that made E3 2011 surprising, momentous and just plain fun.

Microsoft Doubles Down on Halo
Having previously said it would have surprising announcements timed to the 10th anniversary of its first-person shooter, Microsoft didn't shock anyone when it said Halo: Combat Evolved Anniversary would be released Nov. 15. A remastered, retouched version of the killer app that revolutionized FPS games on consoles, Anniversary lets users swap between classic graphics and brand-new ones at any point during their playthroughs.
What people didn't expect at E3 was that 343 Industries, the Microsoft internal dev studio that took over the franchise from Bungie, would officially announce Halo 4 for Christmas 2012. Not the most surprising of announcements — it would be nice if the Xbox 360 maker would announce something besides this and Gears of War — but the first big release in the post-Bungie era is going to be scrutinized carefully.
