If we have NGBC Robert, then we need NGBC Mr.Karate... and he was pretty much identical to 2k2 Ryo initially, except he could also do 2k2 Takuma's Hien, he had Koho Shippuken back, Butt's Kyokugen Koho (Which Mr.Karate in XIII also has) and his Moko Raijin Setsu could OTG. I dunno if that's enough to justify an EX version, unless they amped it up and gave him the aerial firebal and some other stuff, like made cr.B, cr.C a chain like it was in XI, dropped his parries and brought back Biru Bin Kiri, Ryoute Tsuki, then made Tenchi Haoh Ken into a DM/SDM which did more damage on counter-hit and SDM version guaranteed dizzy.
Although I'd rather see regular Ryo get beefed up in someway... I really want the Renbuken back most of all.
