I checked out the other half of the convention as well as checked out other sections in detail.
Nintendo - While I wasn't able to check it out, the Wii-U was apparently not worth the 8-hour wait. From what I saw in the preview videos, it shows some potential. However, the launch titles will either make or break the console and with Nintendo's track record, I fear the latter. Fortunately, the new 3DS titles look pretty amazing. If you haven't played Metal Gear Solid 3, Star Fox 64, or Zelda: Ocarina of Time, I highly recommend you grab them on the 3DS as the updated look and gameplay mechanics add a lot more to the experience. If you have played them, I still recommend them for the nostalgia value at the very least. The new Mario Kart Game for the 3DS looks like a lot of fun, implementing a Kart-customization feature, as well as different terrain in the course, like driving underwater (I'm curious to see how those features will affect races. The Wii's upcoming titles are average at best, however, the one game that really stood out was Zelda: The Skyward Sword, which looks to be an awesome title. Lastly, they announced Fortune Street (aka Itadeki Street) for the DS, which features characters from both the Mario and Dragon Quest franchises in a tricked-out version of monopoly.
Sony of America - Honestly, they didn't have much to offer, as none of the games piqued any interest to me. Their new portable, the Sony Vita, looked interesting. Unfortunately, I was unable to learn anything else about it.
Capcom - Their new Resident Evil games show promise. I was unable to take a look at their 3DS game, but Operation Raccoon City looks like it's going to kick ass. Capcom also announced Street Fighter IV: Arcade Edition, which features improved game mechanics, as well as some new characters, including Yun, Yang, and Evil Ryu. Honestly, though, I think they're giving SFIV the same treatment as SFII with the multiple versions. Lastly, TekkenxStreet Fighter is looks promising.
Namco-Bandai (Cont.) - Ace Combat, aside, I was able to check out some of their other titles. Inversion is going to be a hit-or-miss with most gamers, as it looks to be a Gears of War clone, but with the added feature of a gravity gun, enabling you to stop your enemies from moving as you riddle them with bullets. Another title that had me excited was Galaga DX, celebrating the game's 30th anniversary, which offers a classic mode of the game, as well as a modern rendition of the old classic that plays like a standard top-scrolling shooter, but with the ability to shoot in all directions.
I know there's still 1 more day of E3 left, but not only am I completely exhausted, but I'm also going to be busy tomorrow. My only regret was not being able to check out the preview of The Old Republic Online. Overall, this year was a pretty good show, to say the least.
