Some additional news about the Dreamcast digital downloads came up at E3, but it seems to have slipped under the radar thanks to all the other stuff at the expo. I just learned about this a minute ago. Gaming news website/magazine CVG asked the president of Sega West how many Dreamcast titles would be available digitally by June 2011.
He said they plan to have around "18 to 24" titles! He also stated that this is an effort to focus on the popularity of the Dreamcast, so there are no plans to do this for Saturn titles.

It seems like Sega is really going to go all out in bringing some of the Dreamcast's glory back. It's a pity that the Saturn isn't included. I'd love to have a chance to get Shining Force III.
