The USK (Unterhaltungssoftware Selbstkontrolle) is quickly over taking the ESRB for the best place to uncover unannounced XBLA titles.

The most recent update to the USK site shows the following for Xbox 360:

EXIT (TAITO Corperation)
06/13/07
Genre: Denkspiel/Puzzle

• Yeah, we knew about that one.

Moving on.

Super Puzzle Fighter 2 Turbo HD Remix (CEG Interactive)
06/13/07
Genre: Arcade

• We definitely knew about this one.

And finally:

Tetris Splash (Microsoft EPDC)
06/13/07
Genre: Arcade

• Didn't know about this one.

Well, to be honest, actually we did know about it. We just didn't know it would be called Tetris Splash.

Anyone mad they just bought Tetris Evolution?

(In case you are wondering about "Microsoft EPDC", it is the European Product Development Centre which is responsible for overseeing the localization of Microsoft products for European markets.)

It's really a shame that the ESRB doesn't have an RSS feed. They are quickly becoming the de facto standard for XBLA leaks. Today, IGN UK brings us the word that Sonic the Hedgehog (I assume the classic version) has been submitted to the ESRB for a rating. This supports the "rumor" (when do they ever turn out to be false?) that classic Sonic was on its way to XBLA via a SEGA Vintage Collection.

The new bit though was the additional submission of Ecco the Dolphin. Looks like animal lovers of the Genesis age can begin their celebrations...and their waiting.
