As of right now, we know that 15 titles are being included in the SEGA Ages lineup. We don't know what all those titles are, but they will be revealed as we get closer to Summer. Today we learn that lineup could expand if the initial batch of titles is successful. SEGA has said they'd like to expand the library of games to both Saturn and Dreamcast titles, but they'll need to see consumer support from the first handful of titles before moving ahead on that.
Space Channel 5 would be perfect for this lineup.
I don't have faith, though. Sega have promised to include later gen titles in their collections for a while now and they never do.
Skies of Arcadia Legends HD, please?!
Holy Crap! That would be amazing to play my favorite old Dreamcast and Saturn games on the switch! Please do it now, SEGA!
Jet Set Radio, Skies of Arcadia, Panzer dragoon, Crazy Taxi, Grandia 2

Phantasy Star Online (i know, doubtful) and Skies of Arcadia for sure ...though really prefer the Gamecube versions since they had more content (and othe first one had a 2nd episode and a Plus version)
