EDIT: Also on the matter of the Sonic Origins port, I hope these are the Christan Whitehead ones and not just direct roms. I heard Whitehead's version of Sonic CD is the definitive one.
Regarding Sonic Origins, I strongly suspect Whitehead's involvement considering the SEGA social media manager confirmed the wide-screen aspect ratio on Sonic 3 which is great news.
