UPDATE: Namco Bandai has released a trailer showcasing the swimsuit downloadable content for Tekken Tag Tournament 2.
It's clarified that there are actually over 150 swimsuits in the DLC, available as a pre-order bonus in addition to the Snoop Dogg Stage and additional early access to DLC characters available at ShopTo.net and Zavvi: Michelle Chang, Angel, Kunimitsu or Ancient Ogre.
ORIGINAL STORY: Pre-order Tekken Tag Tournament 2 and you'll get the Big Bikini Bundle, which includes over 100 swimsuits for the bulging roster of playable characters to wear.
That's swimsuits for all characters: male, female and animal. So yes, Kuma in a swimsuit.
Also included are school swimsuits. Tekken chief Katsuhiro Harada said on Twitter (via Andriasang) Namco Bandai expected Japanese players would ask about this, so included them.
Apparently these costumes may be made available post-launch as downloadable content.
The announcement accompanied the release of a Tekken Tag Tournament Girl Power trailer, below.
