At Tokyo Game Show, the spotlight is typically on Japanese developers. However, Battlefield developer DICE will be there with a big reveal.

"This is it! I am going to Tokyo Game Show to showcase Battlefield: Bad Company 2 Vietnam for the first time -- and to spend some quality time with the Japanese Battlefield Community," said community manager zh1nt0 on the game's official blog.

BF:BC2 Vietnam is an expansion pack with 4 new maps as well as Vietnam War era equipment and vehicles. All we've seen of it thus far is a teaser trailer. It's scheduled for a late 2010 release.

This year's Tokyo Game Show runs from September 16th to 19th. It will be held at the Makuhari Messe in Chiba, Japan.
