After months of speculation and rumors, SEGA has officially announced that Dreamcast games will be returning in digital form to Xbox Live Arcade and PlayStation Network later this year.

Sonic Adventure and Crazy Taxi will be the first two titles available this fall, with Sonic Adventure arriving in time or the 11th anniversary launch of the Sega Dreamcast in the US.

Every Dreamcast game will feature “high resolution visuals,” surround sound, online leader boards and Achievements.

“The Dreamcast is fondly remembered by a large community of dedicated fans as a console that was ahead of its time in terms of graphics, quality and online gaming” commented Haruki Satomi, VP of Digital Business at SEGA of America and SEGA Europe.

“There are few things that are more requested from us than making Dreamcast classics available for download in today’s digital market place. We’re very excited to begin offering gamers our beloved Dreamcast titles again on the current console systems.”

Both Sonic Adventure and Crazy Taxi will be on display next week at SEGA’s E3 booth.
