Ok after watching the SFV Gameplay trailer over and over again , i thought about making my own Analysis and put it out here so we can start a discussions here about Street fighter 5 system, and just before I start talking about it, i just want to say that I haven’t read the SRK version before doing this or even known that they posted an analysis, and btw English is not my Native language, so sorry if there is any mistakes,
okay a quick analysis of mine about Street fighter 5, as far as the trailler shows the new game will have Guard Crush and Ryu has Denjin Hadouken super, you can do combos on a knockdown opponent (similar to OTG) , also at 00:59 a Launcher move that sends the opponent in the air (similar to MVC ) , corners wall breaks and thus stage length expands , hmm and there is that system that got watermark effect on ryu and chun li, i m not sure of it but seems like an Enhanced system which sets the character that activates it to threw stronger specials and be more offensive, as you can see at 00:38 chun li activates some sort of system that covers her with blue watermark while posing and then go all combo mode on ryu hmmm , also she even threws a spinning bird kick with the same effect on at 43:00 and yeah it seems that work the same way as an Ex Spinning bird kick, also ryu activates his watermark with black and electric effect at 00:53 and then threws a stronger hadouken that has electrics effect on them and i think it hits twice or was it 3 hits? i m not sure, then you could see his normals even changed and has electric effect on them, hmm nice interesting change to ryu’s crouching medium kick, looks more realistic to me and i like how they made chun li thighs size a bit thin , it looks better imo , graphics looks great and the china stage never been this good, well i m impressed but I hope this is not the final graphics there going with
