I'd say it's about time for new Yosuke Okunari's projects...
ca. 2004-2008: Sega Ages PS2 ports, also Sega Rally PS2 port, Virtual Console stuff
ca. 2009-2013: PS3, X360 ports starting from Virtual On 360 and ending with Jet Set Radio and the Japan only Model 2 games, Light Gun games on Wii (Ghost Squad, L.A. Machinegun, HotD)
ca. 2013-2016: Only 3D Classics
There gotta be more, best to PC/Xbone/PS4
