May 21 is certainly a date to remember and look forward to, and the Call of Duty team is making the anticipation reach even greater heights with the six-seconder teaser that it released via Vine.

In its official Twitter account, the video was posted the tweet below, showcasing screenshots of the game as well as the production and technology behind it, with the last frame announcing, "See it live at the Next Generation Xbox Reveal 5.21.13."

Perhaps Activision was saving the gameplay for the May 21 reveal date, and thought it more appropriate to feature the tech behind it as a teaser--that it may also feature the technology on May 21?

In any case, there's more up the sleeves of the Call of Duty team, this time adding another name to the roster of those prepping the game for its November release.

GameSpot reports that Kevin Flynn, senior product manager for EA UK for two years, has now joined Activision UK to become the senior brand manager for Call of Duty. According to the report, he has been responsible for the likes of Battlefield 3 launching and Premium DLC campaigns.

Battlefield 4: Forgoing next-gen Xbox 720 & PS4?

Unlike most upcoming games, which are either slated for a next-gen release or even an exclusivity deal with one console, Battlefield 4 may be forgoing the next-gen route to focus on the current-gen consoles.

The Examiner reports that the official Battlefield Twitter account has already released word regarding its future with next-gen consoles.

"We are only focusing on PC, Xbox 360, and PlayStation 3 at this point."

Of course, focusing and releasing the game are two very different modes of action, and it may be that, for its fall release, Battlefield 4 is only looking at the three platforms for the meantime.

The BF4 eSports

Though potential next-gen exclusion maybe worrisome news, there is a progressive bit of update with regard to Battlefield 4's multiplayer mode.

BF4.co reports that in an interview with DICE general manager Karl Magnus Troedsson, the multiplayer can pave the way towards a Battlefield 4 eSports.

"I can't talk about the specifics since we're not announcing them, but I can say that e-sports is an area that we are very interested in," said Troedsson to BF4.co.

"It's just recently that it's really started to take off more in semi-mainstream, online media, etc., which is amazingly cool, by the way. So yes, we're very interested in this area, and we're definitely going to see what we can do there."

Just last month, Call of Duty has also held its first annual COD Championship. And with the longstanding battle between the two games, it's not unlikely that Battlefield will put its strong suit to a more diverse playing field.
