Big 3 mimic each other at E3: more, more and more

During their flashy news conferences, Microsoft, Nintendo and Sony all announced plans for more games, more sequels, more exclusives, more connectivity and more ways for gamers to use their systems for stuff other than gaming.

Such an escalation in enhancements is undoubtedly good news for existing owners of the Xbox 360, Wii and PlayStation 3 consoles, as well as their handheld counterparts. However, the upgrades may leave the systems feeling less distinct than ever before. Similar features and comparative accessories could confuse financially strapped consumers looking to power up this holiday season.

Microsoft kicked off E3 Monday at the Los Angeles Convention Center with a ceremony pitching the Xbox 360 as family-friendly. Perhaps the biggest announcement was a redesign of the console's interface, which will allow users to create avatars that can interact with each other and play select games online. The Wii's already had that feature--called Miis--since its 2006 debut.

The parallels only begin there. Microsoft flaunted "Lips," a new sing-along game similar to Sony's popular "SingStar" franchise. Unlike "SingStar," this karaoke game developed by iNiS enables wannabe singers to croon their preexisting tunes from MP3 players and to bust moves with a microphone that's motion sensitive, a feature that's been a hallmark of the Wii.

The next day at the Kodak Theatre in Hollywood, Nintendo unveiled WiiSpeak, a "community microphone" that attaches to the top of the console's sensor bar and will allow users to vocally chat. The WiiSpeak accessory will cost $29.99 and be available later this year. Both the Xbox 360 and PlayStation 3 already feature voice chat capabilities and their own headset microphones.

Nintendo teased the news that new entries in the decades-old "Mario Bros." and "Zelda" franchises were currently in development. And for the first time, Nintendo will bring the "Animal Crossing" series to the Wii with "Animal Crossing: City Folk" later this year. The cutesy open-world game will boast a bigger playing field and an online auction house selling virtual items.

"You're able to just do all the things you love to do in 'Animal Crossing' but even more," said Cammie Dunaway, vice president at Nintendo. "And particularly with the new WiiSpeak peripheral, it just opens up the experience, so that you can be playing in a roomful of people, talking to people somewhere across the world."

At the end of their press conference, Nintendo struck up "Wii Music"--yet another play-along music game but one that uses the Wii's controls instead of instrument-shaped peripherals like "Rock Band" and "Guitar Hero." Nintendo's game will give makeshift musicians the ability to conduct an orchestra as well as simulate playing 40 instruments. That's 36 more than "Rock Band."

Later at the Shrine Auditorium on Tuesday, Sony debuted its long-awaited video download service for the PlayStation 3. Standard and high definition videos from such studios as MGM, Fox, Lionsgate and Disney can be downloaded and watched on the console and transferred to Sony's PlayStation Portable handheld system. Rentals cost $2.99 to $5.99 while purchases range from $9.99 to $14.99.
