This is not just another re-release. It looks like Christian Whitehead, who did the Sonic CD 2011 version may be working on this. It includes a remastered soundtrack, a time attack mode, widescreen and everything runs at a full 60 fps.
EDIT: Also, this comes from a GDC press even where SEGA announced a bunch of iOS/Android stuff. Could be that they just haven't announced the console/PC versions yet.
EDIT 2: Taxman and Stealth from Sonic Retro are confirmed to be working on this.
