Some SFV Ryu stuff:
His cr.mk has a short hitbox, i.e. Ryus foot touching Chuns foot does not hit even when overlapping.
Furthest hitting attack is hk, since it moves him forward but it only hits high.
A relatively good poke is st.mk as second furthest reaching attack, which isn't as ass in USFIV and more like Sagats but not as good as Eryu since it doesn't move him forward.
Cr. lp/lk can no longer combo into mp/mk, but st.lp has enough hit stun to even combo into cr.HP. The drawback is st.lp has pathetic range only hiting as far as second light attack.
F+HP seems to move further than in USFIV and distance might be closer to Codys "solar plexus".
When hitting F+HP from distance cr.mk into mk tatsu is the most reliable combo otherwise just do DP.
B+hk has now enough advantage to combo into st.mp and force stands, so it's preferable to use this when you managed to hit a hard jump in attack.
CC HP knocks down while HK puts he opponent into a spin state that is long enough to dash in and hit with st.lp, as anti-air it puts the opponent into a full air juggle state.
Kara Throws are back it seems. St.mk and b+hk seem to be the farthest by moving Ryu one square.
Neutral jump attack are no longer different from forward/backward jump attacks.
His j.mp juggles opponent and both hits can be canceled into tatsu. Which means you can hit j.mp -> tatsu -> juggle ex dp. It's not consistent though, so you have to watch out how you hit your opponent. Full j.mp combo does like 280 and 350 stun.
Corner crossup is still there and gotten even more ambiguous. If you hit early it doesn't cross up, do it really late and you get a deep cross up.
His mk tatsu now hits crouching opponents and HK tatsu now switches sides on hit. LK tatsu recovers fast enough to follow up with ex dp in corner or Super at specific distances.
Also no cross up air tatsus anymore except EX, but can still hit front.
V-Trigger mode adds more stun and damage to hand based attacks.
V-Trigger super does 350 dmg(50 more than normal) and 300 stun. When hitting opponent with V-Trigger hadoken(sans non charged HP) at full screen you can juggle into super. A fully charged hadoken does 700 stun so if you hit confirm v-trigger super you get 970 stun, due to scaling.
V-Trigger super guard crush is shorter than charged hadoken.
